STRUCTURE OF RIBONUCLEOTIDE REDUCTASE PROTEIN R1
Overview
Ribonucleotide reductase is the only enzyme that catalyses de novo, formation of deoxyribonucleotides and is thus a key enzyme in DNA, synthesis. The radical-based reaction involves five cysteins. Two, redox-active cysteines are located at adjacent antiparallel strands in a, new type of ten-stranded alpha/beta-barrel, and two others at the carboxyl, end in a flexible arm. The fifth cysteine, in a loop in the centre of the, barrel, is positioned to initiate the radical reaction.
