Photolysis of papain which had been inhibited with 2-bromo-2',4'-dimethoxyacetophenone regenerated papain, but also formed [deltaSer25]-papain (i.e. papain in which the active-site cysteine residue 25 was replaced by dehydroserine) via the intermediate dehydrocysteine analogue, [deltaCys25]-papain. Reduction with sodium borohydride gave [Ser25]papain.
