Ribonucleotide reductase (RNR), also known as ribonucleoside diphosphate reductase, is an enzyme that catalyzes the formation of deoxyribonucleotides from ribonucleotides.lass III reductases use a glycine radical generated with the help of an S-adenosyl methionine and an iron sulphur center. Reduction of NTPs is limited to anaerobic conditions. Class III reductases are distributed in archaebacteria, eubacteria, and bacteriophages.
Biotin synthase reductively cleaves SAM into a deoxyadenosyl radicalâa first radical formed on dethiobiotin is trapped by the sulfur donor, which was found to be the iron-sulfur (Fe-S) center contained in the enzyme. Cofactor biochemistry. D-(+)-Biotin is a cofactor responsible for carbon dioxide transfer in several carboxylase enzymes: 1  Acetyl-CoA carboxylase alpha. 2  Acetyl-CoA carboxylase beta. 3  Methylcrotonyl-CoA carboxylase. 4  Propionyl-CoA carboxylase. 5  Pyruvate carboxylase.
