Renilla luciferase (RLUC) is a versatile tool for gene expression assays and in vivo biosensor applications, but its catalytic mechanism remains to be elucidated. RLUC is evolutionarily related to the alpha/beta hydrolase family. Its closest known homologs are bacterial dehalogenases

This work describes the reaction mechanism for chemical modification of tyrosinase by Woodward's Reagent K and its covalent attachment to a glassy carbon electrode. The spectrophotometric studies revealed that the modification does not cause a significant structural change to tyrosinase.

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

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

The organ common-type (CT) isoenzyme of acylphosphatase is inactivated by Woodward's reagent K (WRK) (N-ethyl-5-phenylisoxazolium-3'-sulphonate) at pH6.0. The inactivation reaction follows apparent pseudo first-order kinetics. The dependence of the reciprocal of the pseudo first-order kinetic constant (kobs) on the reciprocal
