Protein

Ribonucleoside-diphosphate reductase 2 subunit beta

Gene

nrdF

Organism
Escherichia coli (strain K12)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

Provides the precursors necessary for DNA synthesis. Catalyzes the biosynthesis of deoxyribonucleotides from the corresponding ribonucleotides. R2F contains the tyrosyl radical required for catalysis.

Catalytic activityi

2'-deoxyribonucleoside diphosphate + thioredoxin disulfide + H2O = ribonucleoside diphosphate + thioredoxin.PROSITE-ProRule annotation

Cofactori

Fe cationBy similarityNote: Binds 2 iron ions per subunit.By similarity

Pathwayi: DNA replication
