| + | [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> | ||

| - | The crystal structures of ADP bound and nucleotide-free forms of molecular chaperone-like diol dehydratase-reactivating factor (DDR) were determined at 2.0 and 3.0 A, respectively. DDR exists as a dimer of heterodimer (alphabeta)2. The alpha subunit has four domains: ATPase domain, swiveling domain, linker domain, and insert domain. The beta subunit, composed of a single domain, has a similar fold to the beta subunit of diol dehydratase (DD). The binding of an ADP molecule to the nucleotide binding site of DDR causes a marked conformational change of the ATPase domain of the alpha subunit, which would weaken the interactions between the DDR alpha and beta subunits and make the displacement of the DDR beta subunit by DD through the beta subunit possible. The binding of the DD beta subunit to the DDR alpha subunit induces steric repulsion between the DDR alpha and DD alpha subunits that would lead to the release of a damaged cofactor from inactivated holoDD. | ||
