Conversion of the active-site cysteine residue of papain into a dehydro-serine, a serine and a glycine residue.

Eur. J. Biochem. 84(1) , 293-9, (1978)

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...
