This database was queried using Escherichia coli GroEL and all hits with an E-value lower than 10−7 were retrieved. The list of hits was manually curated to remove spurious sequences by removing proteins of length greater than 1.5 times that of the query sequence, and/or on the basis of sequence annotation at NCBI, resulting in a final set of 840 GroEL homologues. These proteins were aligned with MUSCLE 3.6 [1] using the default parameters, and a 100-bootstrap maximum35 likelihood phylogenetic tree was created using RAxML 7 [2] under the WAG model of protein sequence evolution [3], which was suggested by ProtTest [4]. The topology of the resulting tree was then used to infer duplication events in GroEL evolution.Sequences were obtained for the mitochondrial Hsp60 analysis by BLASTing the Homo sapiens40 mitochondrial Hsp60 sequence against the NCBI non-redundant database. The resulting hits were retrieved and both automatically and manually curated. Due to the large number of hits to partial or otherwise suspect sequences, all sequences shorter than 450 residues were discarded (this is 120 residues shorter than the H. sapiens sequence). The remaining sequences were aligned with theGroEL sequences of the Rickettsiales, a group of bacteria that may be closely related to the45 ancestral mitochondrion [5], and with a putative outgroup, Bradyrhizobium japonicum. A 100- bootstrap, maximum-likelihood phylogenetic tree was built from this alignment as described above(see Supplementary Figure 1). The topology of this tree suggested that the sequences did indeed fall into three clades (eukaryotic mitochondrial sequences, Rickettsiales, Bradyrhizobium japonicum).Given the evidence supporting the monophyly of the mitochondrion and the Rickettsiales [6], we50 proceeded with our use of Bradyrhizobium japonicum as the outgroup. These sequences were then used in our analysis of functional divergence as described below. Figure S1: Phylogenetic tree of mitochondrial HSP60 sequences. Branches are coloured55 according to the major clades that were compared in our analysis. In line with previous reports, the mitochondrial and Rickettsial groups receive strong bootstrap support.Archaeal homologs of the bacterial group II chaperonin genes were obtained by BLASTing theDesulfotomaculum reducens group II sequence against all archaeal sequences in the NCBI non-60 redundant database, using the default parameters. Non-chaperonin sequences were manually removed from the list of hits, and the remaining sequences were used to construct a phylogeny as described above for the GroEL genes, using the LG model of protein evolution [7]. 65 Figure S2: Phylogenetic tree of group II chaperonin sequences from archaea and bacteria.Bacterial lineages are highlighted in red; major archaeal lineages are coloured to clearly delineate groups. Nine of the ten bacterial sequences form a strongly-supported monophyletic cluster which has two group II sequences from the methanogen Methanosarcina acetivorans as an outgroup. The immediate outgroup of the group II sequence from Oligotropha carboxidivorans is encoded by the70 archaeaon Nanoarchaeum equitans. Testing the pseudogenization of group II chaperonin sequences in bacteriaWe used the method of Yang and Nielsen [8] implemented in the yn00 program, which is part of thePAML package [9], to compare the ratios of nonsynonymous and synonymous substitution rates 75 (dN/dS) between bacterial and archaeal group II chaperonin sequences. The difference between the nonsynonymous and synonymous rate is mainly due to selection, because nonsynonymous changes alter the encoded protein sequence whereas synonymous changes do not. Most protein-changing mutations are deleterious [10], so that the nonsynonymous rate is usually much lower than the synonymous rate in proteins under selective constraint – that is, functional proteins. If the group II 80 chaperonin sequences in bacteria have become nonfunctional, then the mean pairwise dN/dS ratio among bacterial sequences should be substantially higher than that among archaeal sequences. In fact, these ratios were very similar (0.204 for bacteria; for archaea: 0.194), suggesting that the groupII chaperonins are evolving under comparable selective constraints in both domains. Under the assumption that the archaeal group II chaperonin sequences are functional, this result suggests the 85 bacterial sequences are as well.Horizontal gene transfer between group II chaperonin-possessing bacteria and methanogenic archaeaExisting evidence from a variety of sources supports a substantial level of horizontal gene transfer 90 between the 10 bacteria possessing a group II chaperonin gene and the methanogenic archaea (summarized in Supplementary Table 1). The DarkHorse database, which attempts to catalogue horizontally transferred genes [11], suggests that horizontal transfer is ongoing between these species and archaea, with a mean of 46 recently-transferred (DarkHorse LPI score < 0.25) archaeal genes per bacterial genome which contains a group II chaperonin gene. Putative group II 95 chaperonin clients in bacteria would have been transferred somewhat earlier, and should be found in bacterial species with a group II chaperonin gene and archaea, but not other bacteria. Ultimately, experimental work is required to identify clients of the functional archaeal chaperonin in these bacteria.

Starting with the tips of a phylogenetic tree, the software walks130 down to the root, identifying all interior nodes at which a branch-specific analysis of functional divergence can be performed (the analysis is performed if there are at least four sequences in each descendant clade). A test for functional divergence at each of these nodes is then carried out. A node is defined by two clades (clusters) and one or more outgroup sequences, and our method usesBLOSUM scores [12] to identify conserved unexpected substitutions — that is, substitutions135 associated with large, negative BLOSUM scores — in one protein cluster which are not observed in the homologous cluster, or in an outgroup cluster. These sites are then taken to be under functional divergence on the branch leading to that cluster. The procedure is illustrated in SupplementaryFigure 3 above: a section of the multiple sequence alignment being scanned by the method shows a column in which functional divergence is detected. The amino acids are colour-coded following the140 same principle as ClustalX and hence the colours correspond to amino acid properties. In the examples we identify a transition from an ancestral F/Y to a P, which is conserved thereafter, indicating functional divergence (FD). In the next example, a charged amino acid (D/E) mutates to aM/L, also indicating functional divergence. For each column of a protein multiple sequence alignment for which the three clusters are already defined, we calculate four quantities: the mean145 pairwise BLOSUM score between sequences in the first cluster and the outgroup cluster (C1); the mean pairwise BLOSUM score between sequences in the second cluster and the outgroup cluster(C2); and the standard errors (SEC1, SEC2). We then calculate a test score for that column as and assess significance against a normal distribution. The method was previously applied to the evolution of endosymbiotic bacteria [13], with the main improvement here being the ability to150 perform branch-specific tests of functional divergence across a complex phylogenetic tree.Here, we present both a branch-specific, whole phylogeny test (the analysis of all bacterial GroEL genes), and a test of a single lineage (mitochondrial Hsp60). In the case of analyzing the entire tree, we draw a distribution of numbers of sites under functional divergence on each branch, and155 examine the top 5% of the distribution in order to isolate the most important patterns of functional divergence in the dataset. With our analysis of mitochondrial Hsp60, we examine the specific sites identified as being under functional divergence.Importance of sites under functional divergence in mtHsp60160 This section presents the detailed evidence for our claim that the detected functionally divergent sites in mtHsp60 (the mitochondrial GroEL) are of considerable functional importance. Note that, in the following discussion, all residue numbers are given according to their positions in E. coliGroEL: this is due to the far greater body of GroEL mutagenesis experiments that have been conducted in that organism. 165Three of the sites under functional divergence are close to positions that maintain the inter-ring interaction in GroEL (marked in red in Figure 2). V438 is 2.9Å away from E434, L444 is directly beside (1.3Å) R445, and Q453 is again directly beside (1.3Å) R452, all three of which form the interface with the other ring of GroEL [14]. We also identified two other residues in this region,170 V14 and K28, of currently unknown function. Radical change at the inter-ring interface makes sense, since bacterial GroEL operates as a double-ring complex while mtHsp60 does not. Sun et al. [15] isolated mutants of a single-ring GroEL variant (SR1) which restored chaperone function but did not restore the double-ring quaternary structure. That is, they isolated mutations175 resulting in active, single-ring variants of GroEL. Four of the sites detected as being under functional divergence were close to several of these mutants: K390 (under functional divergence) was directly beside (1.3Å) M389, E397 was close to both R395 and A399 (3.1Å in each case),Q505 is close to A503 (3.3Å) and A507 (3.1Å), and I515 is directly between M514 (1.3Å) andT516 (1.2Å). One or more mutations at each of these positions restore single-ring GroEL function180 [56]. Again, the proximity of these sites under functional divergence to sites which, when mutated, result in an active single-ring GroEL mutant makes biological sense in light of the functional differences between mtHsp60 and GroEL.Six additional functionally divergent sites are in positions, which suggest functional importance.185 T210 forms the hinge of a substrate-binding loop in the GroEL apical domain, and also makes contact with other subunits in the same ring [16]. Both this site and the adjacent G211 are under functional divergence in mtHsp60. A239 is beside (1.3Å) E238, which is involved in GroES binding [17]. A241 is involved in substrate binding [18]. R284 forms a salt bridge, which plays an important role in the conformational changes which occur in one half of the GroEL complex upon190 ATP binding [20]. E315 is beside (1.3A) L314, which is involved in substrate binding [16]. The mutagenesis experiments referenced here were performed on E. coli GroEL, and so cannot provide direct information about the function of the homologous positions in mtHsp60. However, the location of these functionally divergent sites in important regions of the GroEL protein suggest that our method has captured, at least partially, the amino acid-level changes responsible for the195 observed differences in function between mtHsp60 and GroEL.Escherichia coli site mtHsp60 (consensus) Rickettsiales (consensus) Bradyrhizobium V14 A E E K28 A K K D121 M D D T210 G K K G211 Q M M A239 L A A A241 N V V A243 Q S S R284 N R R K315 H K K K390 N K K E397 T E E V438 I A A L444 K I I Q453 T Q Q Q505 V Q Q I515 T I V -(179 aln) - M M -(1016 aln) T A A Supplementary Table 2: Sites under functional divergence in mitochondrial Hsp60 (mtHsp60).200 Phylogenetic distribution of groESWe used BLASTP searches against each bacterial and archaeal genome containing one or more groEL genes to check for the co-occurrence of the chaperonin with its accessory protein, GROES.We first performed our search using E. coli GROES, re-running manual BLASTs using a GROES205 query sequence from a more closely-related species if the initial search did not identify any significant hits (defined as an E-value lower than 10-7, coupled with NCBI database annotation).The accession numbers for the hits obtained are provided in Supplementary Table 6. All but four groEL-encoding genomes were shown to contain at least one groES gene with this approach. We reasoned that the remaining four species – the bacteria Escherichia coli APEC O1, Clostridium210 tetani E88, Magnetospirillum magneticum AMB-1, and Lysinibacillus sphaericus C3-41 – might contain an unannotated groES gene, because all four possess typical groEL genes as well as having relatives possessing both groEL and groES. Indeed, TBLASTN searches using the E. coli GROES sequence revealed significant hits in all four genomes. In the case of Lysinibacillus, the hit to the E. coli sequence is at the limit of our criterion (E-value = 10-7), but the genomic location of the hit –215 directly adjacent to groEL – suggests that this is a genuine groES gene. Among the bacteria and archaea we surveyed, then, genomes containing one or more groEL genes also contained at least one groES. Co-occurrence of groEL and groES duplicates 220 Substantially more species contain duplicate groEL (163) than groES (69) genes. Although some groups of bacteria possess elevated copy numbers of both genes (the Rhizobiales and theBurkholderiales), there is no 1:1 ratio in the number of groEL and groES genes, and many species with multiple, functionally divergent GROELs have only a single GROES (e.g. the Chlamydiae,Mycobacteria, and Wolbachia species; see Supplementary Table 6). This result suggests that a225 single GROES can perform its co-chaperonin function for multiple, functionally divergent GROEL complexes.
