Investigation of the catalytic site of actinidin by using benzofuroxan as a reactivity probe with selectivity for the thiolate-imidazolium ion-pair systems of cysteine proteinases. Evidence that the reaction of the ion-pair of actinidin (pKI 3.0, pKII 9.6) is modulated by the state of ionization of a group associated with a molecular pKa of 5.5.

Benzofuroxan reacts with the catalytic-site thiol group of actinidin (EC 3.4.22.14, the cysteine proteinase from Actinidia chinensis) to produce stoicheiometric amounts of the chromophoric reduction product, o-benzoquinone dioxime, and of a catalytically inactive derivative of actinidin that is devo...
