A model for the role of multiple cysteine residues involved in ribonucleotide reduction: amazing and still confusing.
Ribonucleotide reductase from Escherichia coli catalyzes the conversion of nucleotides to deoxynucleotides. Multiple cysteins have been postulated to play a key role in this process. To test the role… Expand
Characterization of C439SR1, a mutant of Escherichia coli ribonucleotide diphosphate reductase: evidence that C439 is a residue essential for nucleotide reduction and C439SR1 is a protein possessing…
Ribonucleotide reductase from Escherichia coli catalyzes the conversion of nucleotides to deoxynucleotides. Cysteine 439 is proposed to be the protein radical on R1 which initiates the reduction… Expand
