The reaction of a class I ribonucleotide reductase (RNR) begins when a cofactor in the β subunit oxidizes a cysteine residue ~35 Å away in the α subunit, generating a thiyl radical. In the class Ic enzyme from Chlamydia trachomatis (Ct), the cyste

A class Ia ribonucleotide reductase (RNR) employs a μ-oxo-Fe2(III/III)/tyrosyl radical cofactor in its β subunit to oxidize a cysteine residue ~35 A away in its α subunit; the resultant cysteine radical initiates substrate reduction. During self-a

We previously used a combination of CW and pulsed-ENDOR protocols to identify the types of protonated oxygen (OHx) species and their disposition within the FeIII/FeIV cluster of Intermediate X, the direct precursor of the essential diferric-tyrosyl r

Despite the current availability of several crystal structures of purple acid phosphatases, to date there is no direct evidence for solvent-derived ligands occupying terminal positions in the active enzyme. This is of central importance, because cata

Crystallographic studies of the hydrogenases (Hases) from Desulfovibrio gigas (Dg) and Desulfovibrio vulgaris Miyazaki (DvM) have revealed heterodinuclear nickel-iron active centers in both enzymes. The structures, which represent the as-isolated (un
