Abstract:		"A sexual pheromone, named the protoplast releasing substance (PRS), was formed by mating type minus cells. PRS activates mating type plus cells and results in the release and fusion of protoplasts within distended conjugation-papilla in paired cells and in the release and disruption of protoplasts in unpaired mating type plus cells. In an agar barrier system, the activation of mating type plus cells was markedly inhibited by treatment with pronase (5-10 micrograms per milliliter), proteinase (100 micrograms per milliliter), and alpha-mannosidase (10 micrograms per milliliter). Trypsin (10-100 micrograms per milliliter) had no effect on the activation in the agar barrier system. The results suggest that PRS is a glycoprotein with pronase-sensitive and trypsin-insensitive structure"
