- | + | == Function == | |
- | + | [https://www.uniprot.org/uniprot/DDRA_KLEOK DDRA_KLEOK] Large subunit of the diol dehydratase-reactivating factor (DDR), which reactivates suicidally inhibited adenosylcobalamin-dependent diol dehydratase (DD, pddA, pddB, pddC). DDR acts as a chaperone, reactivating inactivated DD holoenzyme in the presence of ATP, Mg(2+) and free adenosylcobalamin (AdoCbl), by mediating the exchange of the tightly bound damaged cofactor AdoCbl for a free intact one (PubMed:10529189, PubMed:9405397, PubMed:9920879, PubMed:17916188, PubMed:18586770, PubMed:21040475). Reactivation takes place in two steps: ADP-dependent cobalamin release, then ATP-dependent dissociation of the DD apoenzyme-DDR complex. DDR has weak ATPase activity which is required for DD reactivation (PubMed:10529189, PubMed:17916188, PubMed:21040475). This subunit contains the adenosine nucleotide binding site (PubMed:16338403). Activates glycerol-inactivated, O2-inactivated holoenzyme and inactivated enzyme-cyanocobalamin complex (PubMed:9920879). Also reactivates glycerol-inactivated hologlycerol dehydratase, a DD isozyme (PubMed:17916188).<ref>PMID:10529189</ref> <ref>PMID:16338403</ref> <ref>PMID:17916188</ref> <ref>PMID:18586770</ref> <ref>PMID:21040475</ref> <ref>PMID:9405397</ref> <ref>PMID:9920879</ref> | |
