Lipid-translocating exporter-like protein; part of the gene cluster that mediates the biosynthesis of hydroxamate-containing siderophores that play a critical role in virulence via intracellular iron acquisition during macrophage infection (PubMed:18404210). Siderophore biosynthesis. Expression seems not to be induced during iron deprivation (PubMed:18404210). Belongs to the lipid-translocating exporter (LTE) (TC 9.A.26.1) family.
