Spectroscopic characterization of the key catalytic intermediate Ni–C in the O2-tolerant [NiFe] hydrogenase I from Aquifex aeolicus: evidence of a weakly bound hydride

Abstract

Ni–C in the O2-tolerant hydrogenase I from Aquifex aeolicus binds a hydride weaker than that in O2-sensitive hydrogenases. This is in line with the enhanced light-sensitivity of Ni–C, greater lability of the hydride complex and increased catalytic redox potentials relevant to bio-H2 oxidation.
