Figure 5From: Kinetics and mechanism of jack bean urease inhibition by Hg2+Inhibition kinetics for jack bean urease in various concentrations of substrate. (a) Course of the substrate reaction. Assay conditions were as described for Figure 1. Numbers denote urea concentration (mg L-1). (b) Semilogarithmic plot of ln ([P]calc – [P] t ) vs. t with the data taken from curves in (a). (c) The apparent forward inactivation rate constants (A) vs. urea concentrations in the presence of Hg2+.Back to article page
