CC   -!- FUNCTION: Serves as a reducing agent for the phage-induced
CC       ribonucleotide reductase, but not for the bacterial ones. This
CC       specificity may be the result of sequence differences around the redox-
CC       active disulfide bond. The oxidized form accepts electrons from
CC       bacterial glutathione and will, in turn, reduce other small disulfides.
CC       Can also be reduced by NADPH and by bacterial thioredoxin reductase.
CC       {ECO:0000269|PubMed:8440680}.
CC   -!- MISCELLANEOUS: The disulfide bond functions as an electron carrier in
CC       the synthesis of deoxyribonucleotides from the corresponding
CC       ribonucleotide.
CC   -!- SIMILARITY: Belongs to the glutaredoxin family. {ECO:0000305}.
CC   -!- CAUTION: As it can also be reduced by thioredoxin reductase, it is also
CC       known as thioredoxin. {ECO:0000305}.
