This chemically demanding reaction, which proceeds via a carbon-centered free radical, is catalyzed by ribonucleotide reductase (RNR). The mechanism has been deemed unlikely to be catalyzed by a ribozyme, …

WebbA proton-coupled electron-transfer from the disulfide radical to the substrate generates a 3'-deoxynucleotide radical, and the final product is formed when the hydrogen atom that was initially removed from the 3'-position of the nucleotide by the thiyl radical is returned to the same position. WebbThe synthesis of adenosylcobalamin-dependent ribonucleoside-triphosphate reductase (RtpR) and deoxyadenosine kinase/deoxyguanosine kinase was strongly downregulated upon aeration (−2.0 and −1.1 log 2 protein fold change, respectively). WebbR1 contains the binding sites for both substrates and allosteric effectors and carries out the actual reduction of the ribonucleotide. It also provides redox-active cysteines. … jeanne swanson facebook
