WebJan 1, 2024 · Trypsinogen is a substance that is normally produced in the pancreas and released into the small intestine. Trypsinogen is converted to trypsin. Then it starts the process needed to break down proteins into their building blocks (called amino acids). A test can be done to measure the amount of trypsinogen in your blood. WebStringent specificity of trypsin activity is crucial for protein identification. However, specificity can be compromised by autolysis, which generates pseudotrypsin with a broadened specificity and chymotrypsin-like activity (Keil-Dlouha et al., 1971).

WebTrypsin will cleave after Arginine and Lysine. So setting strictly trypsin is enough as it covers both the amino acids. Primary reason people add LysC into the search settings is because LysC is not inhibited when a proline is next to a Lysine residue while Trypsin is. For some search software, this is built into the Trypsin cleavage rules. http://www.analchem.cn/news/13655
