Protein
Ribonucleoside-diphosphate reductase subunit beta nrdF1
Organism
Mycobacterium tuberculosis (strain ATCC 25618 / H37Rv)
Function
Provides the precursors necessary for DNA synthesis. Catalyzes the biosynthesis of deoxyribonucleotides from the corresponding ribonucleotides (By similarity). Two genes for this protein are present in M.tuberculosis; this is thought to not be the active form. When coexpressed in E.coli with nrdE the 2 proteins do not complement a temperature-sensitive E.coli mutant, whereas the other gene (nrdF2) does complement.
Similarity
Belongs to the ribonucleoside diphosphate reductase small chain family.
