Benzyl p-guanidinothiobenzoate hydrochloride, a new active-site titrant for trypsin and trypsin-like enzymes.
Cook RR, Powers JC. Cook RR, et al. Biochem J. 1983 Nov 1;215(2):287-94. doi: 10.1042/bj2150287. Biochem J. 1983. PMID: 6360155 Free PMC article.
Ellman's reagent has also been successfully employed, allowing measurement at 410 nm. Unlike p-nitrophenyl p'-guanidinobenzoate, the thioester titrant reacts slowly with chymotrypsin A alpha thus eliminating interference by this enzyme in most titrations. ... …
