Estimation of the conserved and variable regions of the HsdS_KpnBI sequence and its homologs. The five putative HsdS homolog sequences (Table 3B) were aligned using the ClustalW program. Amino acid sequences with more than 50% homology as well as 100% homology are also shown. Amino acid sequences used are from top to bottom: M.jannaschii DSM2661 [originally called Methanococcus jannaschii which contains two HsaS proteins (34)], Shewanella oneidensis MR-1 (35), Methanosarcina mazei Go1 (29), KpnBI (this study) and Cyanobacteria Nostoc sp. PCC7120 (36).
