Biochem/physiol Actions
Aculeacin A is a lipopeptide that inhibits β-glucan synthesis in yeasts. The inhibition is due to the selective blockage of glucan synthase.
Aculeacin A, an amphophilic antibiotic, inhibits the biosynthesis of β-glucan by selective blockage of β(1→3) glucan synthase.
Application
Aculeacin A is used to study mutations that lead to antibiotic resistance in Saccharomyces cerevisiae 1, the inhibition of Candida albicans2, and the morphogenetic transformation of Candida albicans when treated 3.
