We have examined the interaction of methyl isocyanide with the purified component proteins of Azotobacter vinelandii nitrogenase (Av1 and Av2). CH3NC was shown to be a potent reversible inhibitor (Ki… (More)
We have examined the reduction of azide by the purified component proteins of nitrogenase (Avl and Av2). One of the two species present in azide solutions, HN3, was shown to be a potent substrate (Km… (More)
Voltammetric studies of the redox behaviour of NADH at a poly(3-methylthiophene) conducting polymer electrode showed a large electrocatalytic effect without the use of electron-transfer mediators.
We have recently investigated the structure and composition of FeMoco by both Mo Kα X-ray absorption spectroscopy (XAS) and O2 degradation and its reactivity with [Fe4S4(Set)4]3−, a synthetic… (More)
Abstract Widespread interest has been evoked in recent years in conducting polymers due to their possibilities in the areas of battery/fuel cell research and electroanalysis. This study is part of a… (More)
Involves a Beer's Law plot calibration, a elutropic series, and microvolumetric techniques.
Abstract The deviations at high concentrations (>10 −5 M) in the calibration curves for the determination of catechol in catechol/ascorbic acid mixtures by flow injection analysis using series… (More)
Abstract Nitrogenase (N 2 ase) is composed of two separately purified proteins, the molybdenum-iron (MoFe) protein and the iron (Fe) protein. Nitrogen fixation requires both proteins, a reductant,… (More)
