Woese6 and Nikos C. Kyrpides1 Abstract Halorubrum lacusprofundi is an extreme halophile within the archaeal phylum Euryarchaeota. The type strain ACAM 34 was isolated from Deep Lake, Antarctica. H. lacusprofundi is of phylogenetic interest because it is distantly related to the haloarchaea that have previously been sequenced. It is also of interest because of its psychrotolerance.

Halorubrum Chaoviator Mancinelli Et Al. 2009 Is a Later, Heterotypic Synonym of Halorubrum Ezzemoulense Kharroub Et Al
TAXONOMIC DESCRIPTION Corral et al., Int J Syst Evol Microbiol 2018;68:3657–3665 DOI 10.1099/ijsem.0.003005 Halorubrum chaoviator Mancinelli et al. 2009 is a later, heterotypic synonym of Halorubrum ezzemoulense Kharroub et al. 2006. Emended description of Halorubrum ezzemoulense Kharroub et al. 2006 Paulina Corral,1 Rafael R. de la Haba,1 Carmen Infante-Domínguez,1 Cristina Sanchez-Porro, 1 Mohammad A. Amoozegar,2 R. Thane Papke3 and Antonio Ventosa1,* Abstract A polyphasic comparative taxonomic study of Halorubrum ezzemoulense Kharroub et al. 2006, Halorubrum chaoviator Mancinelli et al. 2009 and eight new Halorubrum strains related to these haloarchaeal species was carried out. Multilocus sequence analysis using the five concatenated housekeeping genes atpB, EF-2, glnA, ppsA and rpoB¢, and phylogenetic analysis based on the 757 core protein sequences obtained from their genomes showed that Hrr. ezzemoulense DSM 17463T, Hrr. chaoviator Halo-G*T (=DSM 19316T) and the eight Halorubrum strains formed a robust cluster, clearly separated from the remaining species of the genus Halorubrum. The orthoANI value and digital DNA–DNA hybridization value, calculated by the Genome-to-Genome Distance Calculator (GGDC), showed percentages among Hrr. ezzemoulense DSM 17463T, Hrr. chaoviator DSM 19316T and the eight Halorubrum strains ranging from 99.4 to 97.9 %, and from 95.0 to 74.2 %, respectively, while these values for those strains and the type strains of the most closely related species of Halorubrum were 88.7–77.4 % and 36.1– 22.3 %, respectively. Although some differences were observed, the phenotypic and polar lipid profiles were quite similar for all the strains studied. -

Chapter Halocins, Bacteriocin-Like Antimicrobials Produced by the Archaeal Domain: Occurrence and Phylogenetic Diversity in Halobacteriales Afef Najjari, Hiba Mejri, Marwa Jabbari, Haitham Sghaier, Ameur Cherif and Hadda-Imene Ouzari Abstract Members of extremely halophilic archaea, currently consisting of more than 56 genera and 216 species, are known to produce their specific bacteriocin-like pep- tides and proteins called halocins, synthesized by the ribosomal pathway. Halocins are diverse in size, consisting of proteins as large as 35 kDa and peptide “microhalo- cins” as small as 3.6 kDa. Today, about fifteen halocins have been described and only three genes, halC8, halS8 and halH4, coding C8, S8 and H4 halocins respectively have been identified. In this study, a total of 1858 of complete and nearly complete genome sequences of Halobacteria class members were retrieved from the IMG and Genbank databases and then screened for halocin encoding gene content, based on the BLASTP algorithm. A total of 61 amino acid sequences belonging to three halocins classes (C8, HalH4 and S8) were identified within 15 genera with the abun- dance of C8 class. Phylogenetic analysis based on amino acids sequences showed a clear segregation of the three halocins classes. Halocin S8 was phylogenetically more close to HalH4. No clear segregation on species and genera levels was observed based on halocin C8 analysiscontrary to HalH4 based analysis. Collectively, these results give an overview on halocins diversity within halophilic archaea which can open new research topics that will shed light on halocins as marker for haloarchaeal phylogentic delineation.

Discovery of a Novel Methanogen Prevalent in Thawing Permafrost
ARTICLE Received 11 Jun 2013 | Accepted 7 Jan 2014 | Published 14 Feb 2014 DOI: 10.1038/ncomms4212 Discovery of a novel methanogen prevalent in thawing permafrost Rhiannon Mondav1,*,w, Ben J. Woodcroft1,*, Eun-Hae Kim2, Carmody K. McCalley3,w, Suzanne B. Hodgkins4, Patrick M. Crill5, Jeffrey Chanton4, Gregory B. Hurst6, Nathan C. VerBerkmoes6,w, Scott R. Saleska3, Philip Hugenholtz1, Virginia I. Rich2 & Gene W. Tyson1 Thawing permafrost promotes microbial degradation of cryo-sequestered and new carbon leading to the biogenic production of methane, creating a positive feedback to climate change. Here we determine microbial community composition along a permafrost thaw gradient in northern Sweden. Partially thawed sites were frequently dominated by a single archaeal phylotype, Candidatus ‘Methanoflorens stordalenmirensis’ gen. nov. sp. nov., belonging to the uncultivated lineage ‘Rice Cluster II’ (Candidatus ‘Methanoflorentaceae’ fam. nov.). Metage- nomic sequencing led to the recovery of its near-complete genome, revealing the genes necessary for hydrogenotrophic methanogenesis. These genes are highly expressed and methane carbon isotope data are consistent with hydrogenotrophic production of methane in the partially thawed site. In addition to permafrost wetlands, ‘Methanoflorentaceae’ are widespread in high methane-flux habitats suggesting that this lineage is both prevalent and a major contributor to global methane production. In thawing permafrost, Candidatus ‘M. stordalenmirensis’ appears to be a key mediator of methane-based positive feedback to climate warming. 1 Australian Centre for Ecogenomics, School of Chemistry and Molecular Biosciences, University of Queensland, Brisbane 4072, Queensland, Australia. 2 Department of Soil, Water and Environmental Science, University of Arizona, Tucson, Arizona 85721, USA. 3 Ecology and Evolutionary Biology Department, University of Arizona, Tucson, Arizona 85721, USA. -
Archaeology of Eukaryotic DNA Replication
Downloaded from http://cshperspectives.cshlp.org/ on September 25, 2021 - Published by Cold Spring Harbor Laboratory Press Archaeology of Eukaryotic DNA Replication Kira S. Makarova and Eugene V. Koonin National Center for Biotechnology Information, National Library of Medicine, National Institutes of Health, Bethesda, Maryland 20894 Correspondence: [email protected] Recent advances in the characterization of the archaeal DNA replication system together with comparative genomic analysis have led to the identification of several previously un- characterized archaeal proteins involved in replication and currently reveal a nearly com- plete correspondence between the components of the archaeal and eukaryotic replication machineries. It can be inferred that the archaeal ancestor of eukaryotes and even the last common ancestor of all extant archaea possessed replication machineries that were compa- rable in complexity to the eukaryotic replication system. The eukaryotic replication system encompasses multiple paralogs of ancestral components such that heteromeric complexes in eukaryotes replace archaeal homomeric complexes, apparently along with subfunctionali- zation of the eukaryotic complex subunits. In the archaea, parallel, lineage-specific dupli- cations of many genes encoding replication machinery components are detectable as well; most of these archaeal paralogs remain to be functionally characterized. The archaeal rep- lication system shows remarkable plasticity whereby even some essential components such as DNA polymerase and single-stranded DNA-binding protein are displaced by unrelated proteins with analogous activities in some lineages. ouble-stranded DNA is the molecule that Okazaki fragments (Kornberg and Baker 2005; Dcarries genetic information in all cellular Barry and Bell 2006; Hamdan and Richardson life-forms; thus, replication of this genetic ma- 2009; Hamdan and van Oijen 2010). -
