T. Kamachi et al., EFFECT OF HG(II) ON HYDROGENASE ACTIVITY FROM DESULFOVIBRIO-VULGARIS (MIYAZAKI), Journal of molecular catalysis. A, Chemical, 96(3), 1995, pp. 329-333
Effect of Hg(II) on the intact hydrogenase activity from Desulfouibrio
vulgaris (Miyazaki) was studied kinetically. When the hydrogenase was
incubated with Hg(II), the hydrogen evolution rate was strongly inhib
ited. From the absorption spectra of the iron-sulfur cluster(s) and th
e EPR spectra of [3Fe-4S] cluster and Ni center, reaction mechanism is
discussed.
