Biosynthesis of cofactors翻译
WebHowever, coenzymes are actually a type of cofactor. Coenzymes are small, non-protein organic molecules that carry chemical groups between enzymes (e.g. NAD and FAD). Forms easily removed loose bonds. Cofactor is a non-protein chemical compound that tightly and loosely binds with an enzyme or other protein molecules. WebAug 5, 2015 · Vitamin B 12 (cobalamin) is required by humans and other organisms for diverse metabolic processes, although only a subset of prokaryotes is capable of synthesizing B 12 and other cobamide cofactors. The complete aerobic and anaerobic pathways for the de novo biosynthesis of B 12 are known, with the exception of the …
