Yapsin 1
Yapsin 1 (EC 3.4.23.41, yeast aspartic protease 3, Yap3 gene product (Saccharomyces cerevisiae)) is an enzyme.[1][2][3] 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
