Acyl-CoA ligase; 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. Targeted to peroxisomes via its PTS2-type peroxisomal targeting signal (By similarity). Expression is induced during iron deprivation (PubMed:18404210). Belongs to the ATP-dependent AMP-binding enzyme family.
