CC -!- FUNCTION: Provides the precursors necessary for DNA synthesis.
CC Catalyzes the biosynthesis of deoxyribonucleotides from the
CC corresponding ribonucleotides. {ECO:0000256|PIRNR:PIRNR000355}.
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-
