Terminally branched long-chain fatty acid biosynthetic pathways and its regulation in B. subtilis. IlvE: branched-chain aminotransferase; BKD: branched-chain α-keto acid dehydrogenase: BKD is composed of two E1 subunits (E1α: dehydrogenase; E1β: decarboxylase, encoded by bkdAA and bkdAB), one E2 subunit (lipoamide acyltransferase, encoded by bkdB), and one E3 subunit (dihydrolipoamide dehydrogenase, encodedby lpdV); FabH: β-ketoacyl-acyl carrier protein synthase III; FASII: type II fatty acid synthase (FabG, FabA/FabZ, FabI, and FabB/FabF); TE: thioesterase. Repression is show by red lines, and activation is shown by a green arrow
