Alignment of protein sequences homologous to the E. coli dephospho-CoA kinase sequence. Six protein sequences exhibiting high homology to the E. coli dephospho-CoA kinase sequence identified from the WIT genomic database (15) were aligned by using ClustalW (21). Ec, E. coli (WIT database no. REC04326); Bs, Bacillus subtilis (RBS02900); Ss, Synechocystis sp. (RCY14763); Ce, Caenorhabditis elegans (RCE05784); Sc, Saccharomyces cerevisiae (RSC03337); Ta, Thermus aquaticus (sp/Q56416); Hs, Homo sapiens (RHS05130). Asterisks indicate identical residues, colons indicate highly conserved residues; and periods indicate less highly conserved residues. The kinase motif of the E. coli sequence is underlined.
