CC   -!- FUNCTION: Provides the precursors necessary for DNA synthesis.
CC       Catalyzes the biosynthesis of deoxyribonucleotides from the
CC       corresponding ribonucleotides (By similarity). {ECO:0000250}.
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   -!- COFACTOR:
CC       Name=Fe cation; Xref=ChEBI:CHEBI:24875; Evidence={ECO:0000250};
CC       Note=Binds 2 iron ions per subunit. {ECO:0000250};
CC   -!- SUBUNIT: Tetramer of two alpha and two beta subunits. {ECO:0000250}.
CC   -!- MISCELLANEOUS: This gene has an intron within which is encoded YosQ, a
CC       putative homing endonuclease.
CC   -!- SIMILARITY: Belongs to the ribonucleoside diphosphate reductase small
CC       chain family. {ECO:0000305}.
