Characterization of a new antibiotic of iturin group: Bacillomycin D.

Abstract
The characterization of an antibiotic isolated from a strain of Bacillus subtilis revealed that this compound is a new antifungal antibiotic of the iturin group. It contains a lipid moiety which is a mixture of 3-amino 12-methyl tridecanoic acid (40%) and 3-amino 12-methyl tetradecanoic acid (60%) and a peptide moiety: L-Asp1, D-Asp1, L-Glu1, L-Pro1, D-Ser1, L-Thr1 and D-Tyr1. These two moieties are joined by a threonyl-β-aminoacid linkage.
