| Description | Pepsin, an acidic protease, is the principal proteolytic enzyme of vertebrate gastric juice. Its inactive precursor, pepsinogen, is produced in stomach mucosa. Pepsin has a broad range of substrates and demonstrates an esterase activity. There are several minor pepsins designated ``B'', ``C'', and ``D''; the major component is ``A'' to which the following data applies. They are chromatographically separable. Conversion of pepsinogen to pepsin, which involves releasing a peptide, may be an autocatalytic process involving self-cleavage by the zymogen. Peptides released on activation have pepsin inhibitory activity. Activity: 2500-3000u/mg Molecular Weight: ~35,000 Optimum pH: Approximately 1.0 for such substrates as casein or hemoglobin if the substrate is native. Extinction Coefficient: 14.7 Isoelectric Point: pH 1.0 Isoionic Point: 2.2-3.0 Inhibitors: Substrate-like epoxides Solubility: Soluble at 0.5mg/ml in 0.01M HCl to give a clear colorless solution. Assay Method: The rate of hydrolysis of |
