Yapsin 1

Yapsin 1 (, yeast aspartic protease 3, Yap3 gene product (Saccharomyces cerevisiae)) is an enzyme. This enzyme catalyses the following chemical reaction


 * Hydrolyses various precursor proteins with Arg or Lys in P1, and commonly Arg or Lys also in P2. The P3 amino acid is usually non-polar, but otherwise additional basic amino acids are favourable in both non-prime and prime positions

This enzyme belongs to the peptidase family A1 of pepsin.
