Evolutionary Conservation Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf. Publication Abstract from PubMedThe S-adenosylmethionine (SAM)-dependent O-methyltransferase from Leptospira interrogans (LiOMT) expressed by gene LA0415 belongs to the Methyltransf_3 family (Pfam PF01596). In this family all of the five bacterial homologues with known function are reported as SAM-dependent O-methylstransferases involved in antibiotic production. The crystal structure of LiOMT in complex with S-adenosylhomocysteine reported here is the first bacterial protein structure in this family. The LiOMT structure shows a conserved SAM-binding region and a probable metal-dependent catalytic site. The molecules of LiOMT generate homodimers by N-terminal swapping, which assists the pre-organization of the substrate-binding site. Based on the sequence and structural analysis, it is implied by the catalytic and substrate-binding site that the substrate of LiOMT is a phenolic derivative, which probably has a large ring-shaped moiety.
