Figure 1. Structure of Aureobasidin A. Aureobasidin A (MW 1,100) is a cyclic depsipeptide antibiotic isolated from the fungus, Aureobasidium pullulans R106. AbA inhibits the product of the yeast AUR1 gene (inositol phosphorylceramide synthase) and is toxic to S. cerevisiae at low concentrations (0.1 ¥ìg/ml). A dominant mutant allele, AUR1-C, confers resistance to AbA, and its expression can be used as a selectable marker.
