Protein

Ribonucleoside-diphosphate reductase subunit alpha

Gene
nrdE, MG231
Organism
Mycoplasma genitalium (strain ATCC 33530 / G-37 / NCTC 10195)
Status
Reviewed - Annotation score: 3 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.

Catalytic activityi

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

Enzyme regulationi

Under complex allosteric control mediated by deoxynucleoside triphosphates and ATP binding. 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 By similarity.
