A novel inactivation mechanism of the NAD-dependent hydrogenase from Alcaligenes eutrophus Z1 comprising redox-dependent steps is described. The model of the hydrogenase inactivation process is proposed which implies that the enzyme may exist in several forms which differ in their stability and spectral properties. One of these forms, existing within a limited (approximately -200 +/- 30 mV) potential range, undergoes a rapid and irreversible inactivation. The dissociation of the FMN prosthetic group from the apohydrogenase appears to be the main reason for the enzyme inactivation. The rationale for the enzyme stabilization under real operational conditions based on the chemical modification of the hydrogenase molecule is suggested.
