Polyclonal Rabbit Affinity Purified B
Pepsins are aspartic proteases that are synthesized in the gastric mucosa and secreted into the stomach. They are released as zymogens called pepsinogens and then converted to active pepsins by the acidic pH of gastric juices. PGA 3, PGA4, and PGA5 are human Pepsinogen A isozymogens that differ in sequence by 2-4aa. Human PGA5 cDNA encodes 388aa including a 15aa signal sequence, a 47aa activation peptide, and a 326aa active enzyme. Human pepsinogen A isozymogens share ~56% aa sequence identity with mouse and rat pepsinogen A isozymogens. Pepsins have optimal activity under conditions of acidic pH and are inhibited by pepstatin. Pepsin A has broad substrate specificity, but preferentially cleaves peptide bonds involving aromatic and aliphatic aa's.
