kinetic isotope effects studies with deuterated histidinols on Salmonella typhimurium HDH reveals that the rate constants obtained at pH 9.0 allow kinetic simulations indicating a thermodynamically unfavorable but relatively fast hydride transfer from histidinol, and an irreversible and slower second hydride transfer from a histidinal derivative |
