摘要：

A mixed valent form of the iron cluster (Fe(II)Fe(III)) in the B2 protein of ribonucleotide reductase has been isolated and characterized. The irons in this state of the protein are ferromagnetically coupled as indicated by the observation of a novel S = 9/2 EPR spectrum. This is the first ferromagnetically coupled Fe(II)Fe(III) cluster reported for a protein and the first observation of the mixed valence form of ribonucleotide reductase. © 1991 Academic Press, Inc.
