In this study we investigate the active-site structure and the catalytic mechanism of clostripain by using a combination of three separate techniques: affinity labelling, site-directed mutagenesis and molecular modelling. A benzamidinyl-diazo dichlorotriazine dye (BDD) was shown to act as an efficient active site-directed affinity label for Clostridium histolyticumclostripain. The enzyme, upon incubation with BDD in 0.1MHepes/NaOHbuffer pH 7.6, exhibits a time-dependent loss of activity.
