    We have cloned the alpha-agglutinin structural gene, AG alpha 1, by the isolation of alpha-specific agglutination-defective mutants, followed by isolation of a complementing plasmid...

    Several adhesins are induced by pheromones during mating in Saccharomyces cerevisiae, including Aga1p, Aga2p, Sag1p (Agalpha1p), and Fig2p...

    ..Complementation analysis showed that sag1 and ag alpha 1, the latter being a previously reported alpha-specific mutation, were mutations in the same gene.

    ..These correlations clearly suggest that GPI-attached proteins have two different signals which act positively or negatively in cell wall incorporation for their cellular localization. ..

    ..Together, these observations imply that short sequences of high helical propensity are constrained to a beta-rich state by covalent and local charge interactions under native conditions, but form helices under non-native conditions. ..

    ..We suggest that partial dependence of the isw2Delta MATalpha invasion on Fus3p and Aga1p corresponds to a weaker pheromone response of this mutant. ..

    ..An induced-fit model of binding with substantial apposition of hydrophobic surfaces on the two ligands can explain the observed affinity, kinetics, and specificity and the conformational effects of the binding reaction. ..
