anaerobic ribonucleoside-triphosphate reductase complex
anaerobic ribonucleoside-triphosphate reductase complex
"An enzyme complex composed of 4 subunits, 2 copies of the large protein (nrdD in E. coli) and 2 copies of the small protein (nrdG in E. coli). It catalyzes the generation of 2'deoxyribonucleotides under anaerobic growth conditions. The larger subunit is the catalytic unit that is activated by the smaller iron-binding subunit."
