Abstract Three analogues of the peptidyl pheromone, α pheromone of Saccharomyces kluyveri, synthesized based on the amino acid sequence proposed by Sato et al. (Agric Biol Chem 45:1531–1533, 1981) were tested for both shmoo-inducing and agglutinability-inducing actions. Purified natural α pheromone of the yeast showed the highest activity among the peptides tested. When methionine in the peptides was oxidized, the activity decreased significatly. α Pheromone of S. kluyveri induced sexual agglutinability in a cells of Saccharomyces cerevisiae, and shmoo in a cells of S. cerevisiae and S. kluyveri. a Pheromone of S. kluyveri had no agglutinability-inducing action on α cells of S. cerevisiae. a Cells of S. kluyveri inactivated only α pheromone of the same species, but a cells of S. cerevisiae inactivated α pheromones of both S. cerevisiae and S. kluyveri.
