General Information
General Information
Commentary
Organism
physiological function
the enzyme is the actual ribonucleoside triphosphate reductase in the oxygen-sensitive ribonucleoside triphosphate reductase system. The reaction requires an auxiliary protein dA1 of 29000 Da, S-adenosylmethionine, NADPH (with NADH as a less active substitute), dithinthreitol, and magnesium ions, and is strongly stimulated by ATP
