1. Single crystal EPR studies of the reduced active site of [NiFe] hydrogenase from Desulfovibrio vulgaris Miyazaki F

Author

Subjects

Abstract

The issue concerning several matters in hydrogenase research, namely the formal oxidation states of nickel in all its paramagnetic intermediate state, the structure of the [NiFe] cluster, including the type of the third bridging ligand between the metals and the functional role of the active center of the enzyme in the hydrogen conversion process is addressed. The various experimental and theoretical considerations indicate a plausible assignment of the g tensors to a specific site.

Abstract

The carbon monoxide complex of [NiFe] hydrogenase from Desulfovibrio vulgaris Miyazaki F is characterized by X-ray crystallography and absorption and resonance Raman spectroscopy. Nine crystal structures of the of [NiFe] hydrogenase in the CO-bound and CO-liberated forms are determined at 1.2,-1.4 A resolution.

Abstract

Several studies are conducted to explain the x-ray crystallographic structure of the R2F subunit present in the ribonucleotide reductase (RNR) of Corynebacterium ammoniagenes. Managanese is shown to play an extremely significant role in the discussed radical formation process.
