The crystal structure of Bacillus subtilis YtqB in complex with SAMThe crystal structure of Bacillus subtilis YtqB in complex with SAM
Structural highlights
FunctionPublication Abstract from PubMedS-adenosyl-l-methionine (SAM)-dependent methyltransferases (MTases) methylate diverse biological molecules using a SAM cofactor. The ytqB gene of Bacillus subtilis encodes a putative MTase and its biological function has never been characterized. To reveal the structural features and the cofactor binding mode of YtqB, we have determined the crystal structures of YtqB alone and in complex with its cofactor, SAM, at 1.9A and 2.2A resolutions, respectively. YtqB folds into a beta-sheet sandwiched by two alpha-helical layers, and assembles into a dimeric form. Each YtqB monomer contains one SAM binding site, which shapes SAM into a slightly curved conformation and exposes the reactive methyl group of SAM potentially to a substrate. Our comparative structural analysis of YtqB and its homologues indicates that YtqB is a SAM-dependent class I MTase, and provides insights into the substrate binding site of YtqB.
