Cysteine endoprotease
WebBromelain (EC 3.4.22.32) is a cysteine endoprotease derived from pineapple stems that randomly hydrolyzes internal peptide bonds to breaks down proteins into peptides [16]. ... WebEP-B2, being a cysteine protease, is optimally active at low pH, is resistant to pepsin but lyzed at physiological concentrations of trypsin, and has good specificity for the sequence QXP, which is abundant in immunotoxic gluten sequences. These factors make it a good fit for enzymatic degradation of immunogenic peptides in an acidic pH [132].
