The steady-state kinetics of formaldehyde dehydrogenase from human liver have been explored. Non-linearities were obtained in v-versus-v[S] plots. It was necessary and sufficient to consider two reactants of the equilibrium mixture of formaldehyde, glutathione and their hemimercaptal adduct for a complete description of the kinetics. A random sequential reaction scheme is proposed in which adduct and beta-NAD+ are the substrates. In addition, glutathione can bind to an allosteric regulatory… CONTINUE READING
