Electron transfer associated with oxygen activation in the B2 protein of ribonucleotide reductase from Escherichia coli.

The Journal of biological chemistry - 15 Oct 1991

Elgren T E, Lynch J B, Juarez-Garcia C, Münck E, Sjöberg B M, Que L

Abstract excerpt

Each of the two beta peptides which comprise the B2 protein of Escherichia coli ribonucleotide reductase (RRB2) possesses a nonheme dinuclear iron cluster and a tyrosine residue at position 122. The oxidized form of the protein contains all high spin ferric iron and 1.0-1.4 tyrosyl radicals per RRB2 protein. In order to define the stoichiometry of in vitro dioxygen reduction catalyzed by fully reduced RRB2 we...
