Protein

Ribonucleoside-diphosphate reductase large subunit

Gene

rnrA

Organism
Dictyostelium discoideum (Slime mold)
Status
Reviewed - Annotation score: 4 out of 5- Protein inferred from homologyi

Functioni

Provides the precursors necessary for DNA synthesis. Catalyzes the biosynthesis of deoxyribonucleotides from the corresponding ribonucleotides (By similarity).By similarity

Catalytic activityi

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

Enzyme regulationi

Under complex allosteric control mediated by deoxynucleoside triphosphates and ATP binding to separate specificity and activation sites on the large subunit. The type of nucleotide bound at the specificity site determines substrate preference. It seems probable that ATP makes the enzyme reduce CDP and UDP, dGTP favors ADP reduction and dTTP favors GDP reduction. Stimulated by ATP and inhibited by dATP binding to the activity site (By similarity).By similarity
