The biosynthesis of the lipopeptide antibiotic surfactin was studied in whole cells of Bacillus subtilis ATCC 21332 which incorporate 14C‐labeled precursor amino acids directly into the product. [14C]Acetate appeared in the fatty acid portion of surfactin and was also partially converted into leucine. An enzyme was isolated and partially purified from a cell‐free extract of the bacillus which catalyzes ATP‐Pi‐exchange reactions which are mediated by the amino acid components of surfactin. This activation pattern is consistent with a peptide synthesizing multienzyme which activates its substrate amino acids simultaneously as reactive aminoacyl phosphates.
