The sex-specific glycoprotein agglutination substance, responsible for sexual agglutination, solubilized from the surface of haploid cells of a or a mating type by the autoclave method had the following effects on mating reaction in Saccharomyces cerevisiae. Sexual agglutination was inhibited by the agglutination substance of the opposite mating type in living cells as well as in heat-killed cells. Formation of zygotes was completely inhibited, when both a and a cells were treated with the agglutination substance of the opposite mating type. The a and a agglutination substances were inactivated by cells of the opposite mating type, with the degree of inactivation being greater for the former. The enzyme responsible for the inactivation of a agglutination substance seems to be carboxypeptidase Y.
