Maize leaf NADP-malic enzyme was rapidly inactivated by micromolar concentrations of Woodward's reagent K (WRK). The inactivation followed pseudo-first order reaction kinetics. The order of reaction with respect to WRK was 1, suggesting that inactivation was a consequence of the

Effects of several chemical probes selectively modifying various amino-acid residues on the activity of UDP-glucose : solasodine glucosyltransferase from eggplant leaves was studied. It was shown that diethylpyrocarbonate (DEPC), a specific modifier of histidine residues, was strongly inhibitory. However, in

Chloride is the allosteric effector of vertebrate pancreatic and salivary alpha-amylases and of the bacterial alpha-amylase from Alteromonas haloplanctis. Activation experiments of A. haloplanctis alpha-amylase by several monovalent anions show that a negative charge, not restricted to that of Cl-

A number of relevant properties of Woodward's reagent K have been determined, such as the stability of the reactant and the optimal reaction conditions of the reactant with protein carboxylates. A Woodward's reagent K stock solution was stable at 4

The reaction of Woordward's reagent K (WRK) with model amino acids and proteins has been analyzed. Our results indicate that WRK forms 340-nm-absorbing adducts with sulfhydryl- and imidazol-containing compounds, but not with carboxylic acid derivatives, in agreement with Liamas et
