A number of biologically important proteolytic enzymes, particularly those involved in the reactions of blood coagulation and fibrinolysis, have the ability to hydrolyze synthetic esters of the basic amino acids, arginine, and lysine. Though synthetic amino acid esters have been used for the study of the reaction kinetics of these enzymes and for assay purposes, relatively little has been done to characterize these enzymes on the basis of their differing abilities to hydrolyze synthetic substrates. Utilizing a variety of comparably substituted arginine and lysine esters, observations were made on the reaction kinetics of several basic amino acid esterases; significant differences were noted among these enzymes, sufficient to establish their separate identity. Further characterization of the reaction of thrombin with synthetic substrates revealed that this enzyme readily hydrolyzes various substituted lysine esters as well as arginine esters. The highest Vmax was observed for the throm-bin-carbobenzoxy-lysine methyl ester reaction but the greatest affinity was observed with benzoyl-arginine methyl ester. The data also clearly establish enzymatic differences between human and bovine thrombin, and between the latter and bovine plasma thrombokinase.

<p><i>Operando</i> spectroelectrochemical analysis is used to determine the water oxidation reaction kinetics for hematite photoanodes prepared using four different synthetic procedures. Whilst these photoanodes exhibit very different current / voltage performance, their underlying water oxidation kinetics are found to be almost invariant. Lower photoanode performance was found to correlate with the observation of optical signals indicative of charge accumulation in mid-gap oxygen vacancy states, indicating these states do not contribute directly to water oxidation.</p>

The course of the conversion of methanol with water vapour was followed on a low-temperature Cu-Zn-Cr-Al catalyst at pressures of 0.2 and 0.6 MPa. The kinetic data were evaluated together with those obtained at 0.1 MPa and the following equation for the reaction kinetics at the given conditions was derived: r = [p(CH3OH)p(H2O)]0.5[p(H2)]-1.3.
