Multiple sequence alignment of saFabH and other bacterial homologues. The amino acid sequence of saFabH is compared with those of bFabH1, ecFabH, and mtFabH. Positions are numbered based on the sequence of ecFabH. The conserved triad (Cys 112, His 244, and Asn 274) at the enzyme active site is in bold face. The asterisks denote sequence identities, and the dots denote sequence similarities.
