one-carbon truncation of the elongating skeleton. This enzymatic editing reaction occurs in the first round of lipopeptide extension and modification involving the multienzymes BarE and BarF, which successively house an NRPS module to initiate the biosynthesis and a PKS module to catalyze the first round of chainextension. Starting with processing a leucine-derived α-ketoacyl starter, the ketosynthase
