CC -!- FUNCTION: Provides the precursors necessary for DNA synthesis.
CC Catalyzes the biosynthesis of deoxyribonucleotides from the
CC corresponding ribonucleotides. R2 contains the tyrosyl radical required
CC for catalysis.
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:0000255|PROSITE-ProRule:PRU10014};
CC -!- COFACTOR:
CC Name=Fe cation; Xref=ChEBI:CHEBI:24875;
CC Note=Binds 2 iron ions per subunit.;
CC -!- ACTIVITY REGULATION: Inhibited by hydroxyurea, leads to dNTP depletion,
CC replication fork arrest and genomic instability.
CC {ECO:0000305|PubMed:20005847}.
CC -!- SUBUNIT: Tetramer of two alpha (R1) and two beta (R2) subunits. The B1
CC protein is a dimer of alpha subunits. A radical transfer pathway occurs
CC between Tyr-123 of R2 and R1.
CC -!- INTERACTION:
CC P69924; P0A6Y8: dnaK; NbExp=2; IntAct=EBI-555196, EBI-542092;
CC P69924; P00452: nrdA; NbExp=11; IntAct=EBI-555196, EBI-370018;
CC P69924; P69924: nrdB; NbExp=5; IntAct=EBI-555196, EBI-555196;
CC -!- INDUCTION: Induced 4.2-fold by hydroxyurea (at protein level).
CC {ECO:0000269|PubMed:20005847}.
CC -!- MISCELLANEOUS: E.coli produces two separate class I enzymes. This one
CC is the functional enzyme during growth.
CC -!- MISCELLANEOUS: A substrate-binding catalytic site, located on R1, is
CC formed only in the presence of the second subunit R2.
CC -!- SIMILARITY: Belongs to the ribonucleoside diphosphate reductase small
CC chain family. {ECO:0000305}.
