Barrierpepsin
Barrierpepsin (EC 3.4.23.35, barrier proteinase, Bar proteinase) is an enzyme.[1][2] This enzyme catalyses the following chemical reaction
- Selective cleavage of -Leu6-Lys- bond in the pheromone alpha-mating factor
This endopeptidase is present in baker's yeast (Saccharomyces cerevisiae).
