Most distant seq: 35% Furthermore, 3% of residues show as conserved in this alignment. The alignment consists of 96% eukaryotic ( 62% vertebrata, 12% arthropoda, 1% fungi, 3% plantae), and 1% viral sequences. (Des- criptions of some sequences were not readily available.) The file containing the sequence descriptions can be found in the attachment, under the name 1yz4A.descr. 2.3 Residue ranking in 1yz4A The 1yz4A sequence is shown in Fig. 1, with each residue colored according to its estimated importance. The full listing of residues in 1yz4A can be found in the file called 1yz4A.ranks sorted in the attachment. 2.4 Top ranking residues in 1yz4A and their position on the structure In the following we consider residues ranking among top 25% of residues in the protein . Figure 2 shows residues in 1yz4A colored by their importance: bright red and yellow indicate more conser- ved/important residues (see Appendix for the coloring scheme).
