CC -!- FUNCTION: Catalyzes the reduction of ribonucleotides to
CC deoxyribonucleotides. May function to provide a pool of
CC deoxyribonucleotide precursors for DNA repair during oxygen limitation
CC and/or for immediate growth after restoration of oxygen.
CC {ECO:0000256|RuleBase:RU364064}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=[thioredoxin]-disulfide + a 2'-deoxyribonucleoside 5'-
CC diphosphate + H2O = [thioredoxin]-dithiol + a ribonucleoside 5'-
CC diphosphate; Xref=Rhea:RHEA:23252, Rhea:RHEA-COMP:10698, Rhea:RHEA-
CC COMP:10700, ChEBI:CHEBI:15377, ChEBI:CHEBI:29950, ChEBI:CHEBI:50058,
CC ChEBI:CHEBI:57930, ChEBI:CHEBI:73316; EC=1.17.4.1;
CC Evidence={ECO:0000256|ARBA:ARBA00000206,
CC ECO:0000256|RuleBase:RU364064};
CC -!- COFACTOR:
CC Name=adenosylcob(III)alamin; Xref=ChEBI:CHEBI:18408;
CC Evidence={ECO:0000256|ARBA:ARBA00001922,
CC ECO:0000256|RuleBase:RU364064};
CC -!- SIMILARITY: Belongs to the ribonucleoside diphosphate reductase class-2
CC family. {ECO:0000256|ARBA:ARBA00007405, ECO:0000256|RuleBase:RU364064}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
CC {ECO:0000313|EMBL:KKQ36175.1}.
