== Publication Abstract from PubMed ==
 +
Trypsin, a serine protease enzyme plays a pivotal role in digestion and is autocatalytic. The crystal structure of a complex formed between porcine trypsin and an auto catalytically produced peptide is reported here. This complex shows a reduction in enzyme activity as compared to native beta-trypsin. The nonapeptide has a lysine, which is recognized by Asp 189 at the specificity pocket. The auto catalytically produced native nonapeptide is bound at the active site cleft like other trypsin inhibitors but the important interactions with the oxyanion hole are absent. The peptide covers only a part of the active site cleft and hence the enzyme activity is reduced rather than being inhibited.
