Ribonucleotide reductase characteristics
WebbThe nature of the amino acids whose codons border introns in ferritin genes is novel; the disposition of these intron boundaries within the three-dimensional structure of the 24-subunit molecule differs significantly from that of other proteins. These observations are discussed in relation to the functions of isoferritins. WebbRibonucleotide reductases (RNRs) catalyze an essential step in DNA biosynthesis, the conversion of ribonucleotides to deoxyribonucleotides. RNR inhibition reduces cellular …

WebbHow the niche controls MuSC fate remains unclear. Ribonucleotide reductase M2B (Rrm2b) modulates MuSC quiescence/differentiation in muscle in response to injury. Rrm2b knockout in myofibers, but not in MuSCs, led to weakness of muscles, such as a loss of muscle mass and strength.
