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. WebSep 5, 2016 · Trypsinogen wird im Pankreas produziert und mit dem Pankreassekret in das Duodenum abgegeben. Dort wird durch eine Enterokinase ein Hexapeptid (Val-Asp-Asp-Asp-Asp-Lys) abgespalten, und Trypsinogen so in das aktive Trypsin überführt. Dieser Vorgang verhindert die proteolytische Aktivität des Enzyms bereits im Pankreas. canning vs freezing peaches
