Susceptibility of the interchain peptide of a bromelain inhibitor precursor to the target proteases bromelain, chymotrypsin, and trypsin
{{output}}
Bromein, a cysteine proteinase inhibitor from pineapple stem, is a unique double-chain inhibitor. The 27.5-kDa precursor protein is processed by the removal of three interchain, two interdomain, and two terminal-flanking peptides, thus resulting in the release... ...
