E., and Cronan, J. E. (2010) Nat. Chem. Biol. 6, 682-688). BioC was believed to be an O-methyltransferase that methylated the free carboxyl of either malonyl-CoA or malonyl-acyl carrier protein based on the ability of O-methylated (but not unmethylated) precursors to bypass the BioC requirement for biotin synthesis both in vivo and in vitro. However, only indirect proof of the hypothesized enzymatic activity was obtained because the activities of the available BioC preparations were too low for direct enzymatic assay. Because E. coli BioC protein was extremely recalcitrant to purification in an active form, BioC homologues of other bacteria were tested. We report that the native form of Bacillus cereus ATCC10987 BioC functionally replaced E. coli BioC in vivo, and the protein could be expressed in soluble form and purified to homogeneity. In disagreement with prior scenarios that favored malonyl-CoA as the methyl acceptor, malonyl-acyl carrier protein was a far better acceptor of methyl groups from S-adenosyl-L-methionine than was malonyl-CoA. BioC was specific for the malonyl moiety and was inhibited by S-adenosyl-L-homocysteine and sinefungin. High level expression of B. cereus BioC in E. coli blocked cell growth and fatty acid synthesis."xsd:string |
