Protein

Barrierpepsin

Gene

BAR1

Organism
Saccharomyces cerevisiae (strain ATCC 204508 / S288c) (Baker's yeast)
Status
Reviewed - Annotation score: 4 out of 5- Experimental evidence at protein leveli

Functioni

This protein called "barrier activity" is excreted by yeast cells mating type a. It is probably a protease that cleaves alpha-factor and thus acts as an antagonist of this mating pheromone and establishes optimal pheromone concentration for conjugation.

Catalytic activityi

Selective cleavage of 6-Leu-|-Lys-7 bond in the pheromone alpha-mating factor.
