additional information | 1 equivalent each of 5'-deoxyadenosine and S-adenosyl-homocysteine are produced for each methylation reaction catalyzed by GenK. The S-methyl group from S-adenosyl-L-methionine is transferred to cobalamin and the aminoglycoside product during the course of the reaction. H atom abstraction from C6' of GenX2 is stereoselective for the pro-R site | Micromonospora echinospora | ? | - |
