Hybrid antibiotics with the nikkomycin nucleoside and polyoxin peptidyl moieties.

Abstract excerpt

Acting as competitive inhibitors of chitin synthase, nikkomycins and polyoxins are potent antibiotics against pathogenic fungi. Taking advantage of the structural similarities between these two peptidyl nucleoside antibiotics, genes required for the biosynthesis of the dipeptidyl moiety of polyoxin from Streptomyces cacaoi were introduced into a Streptomyces ansochromogenes mutant producing the nucleoside moiety...
