Treatment of homogenous human prostatic acid phosphatase (orthophosphoric-monoester phosphohydrolase (acid optimum), EC 3.1.3.2) with low concentrations of Woodward's reagent K (N-ethyl-5-phenylisoxazolium-3'-sulfonate) leads to a rapid loss of enzymic activity. The rate of inactivation of the enzyme is reduced in the

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

In this work we show that ryanodine binding to junctional sarcoplasmic reticulum (SR) membranes or purified ryanodine receptor (RyR) is inhibited in a time- and concentration-dependent fashion by prior treatment with the carboxyl reagent dicyclohexylcarbodiimide (DCCD). Exposure of the membrane-bound

L-Threonine dehydrogenase (TDH) from Escherichia coli is rapidly inactivated and develops a new absorbance peak at 347 nm when incubated with N-ethyl-5-phenylisoxazolium-3'-sulfonate (Woodward's reagent K, WRK). The cofactors, NAD+ or NADH (1.5 mM), provide complete protection against inactivation; L-threonine (60
