Ribonucleoside triphosphate reductase (RTPR, EC 1.17.4.2) fromLactobacillus leichmanniiis a 5′-deoxyadenosylcobalamin-dependent (AdoCbl; Coenzyme B12) enzyme. RTPR is also a prototypical adenosylcobalamin-dependent ribonucleotide reductase, one that, as its name indicates, converts ribonucleoside triphosphates (NTP) to deoxyribonucleoside triphosphates (dNTP). Upon substrate binding to RTPR, AdoCbl's cobalt-carbon bond is cleaved to generate cob(II)alamin, 5′-deoxyadenosine, and the cysteine (C408) derived thiyl radical. Five key cysteines (Cys 119, 408, 419, 731, and 736), from among the ten total cysteines, are involved in RTPR's catalytic mechanism.
