This entry represents the large subunit of adenosylcobalamin-dependent diol dehydratases (EC: and glycerol dehydratases (EC: These enzymes are produced by some enterobacteria in response to growth substances. The enzyme have an TIM beta/alpha barrel fold [PMID: 10903944]. Inactivated holoenzymes are reactivated by their own reactivating factors that mediate the ATP-dependent exchange of an enzyme-bound, damaged cofactor for free adenosylcobalamin through intermediary formation of apoenzyme. The reactivation takes place in two steps: (a) ADP-dependent cobalamin release and (b) ATP-dependent dissociation of the resulting apoenzyme-reactivating factor complexes [PMID: 17916188].
