摘要
Fengycin is a cyclic lipopeptidic antibiotic produced nonribosomally by Bacillus subtilis. A fengycin synthetase mutant of B. subtilis F29-3 was generated with Tn917lux, which contains a transposon inserted in a 7716-bp gene, fenD. The mutation can be genetically complemented by transforming a plasmid carrying a wild-type fenD, confirming the participation of the gene in fengycin synthesis. Sequencing and biochemical analysis reveal that this gene encodes an enzyme that includes two amino acid-activating modules, FenD1 and FenD2, which activate L-Tyr and L-Thr, the third and the fourth amino acids in fengycin, respectively.
