What is the function of this protein?
Nonribosomal peptide synthase; part of the siderophore biosynthetic pathway (PubMed:15953695, PubMed:17845073, PubMed:17464044).  Aspergillus fumigatus produces four types of siderophores, low-molecular-mass iron chelators, including excreted fusarinine C (FsC) and triacetylfusarinine C (TAFC) for iron uptake; and intacellular ferricrocin (FC) for hyphal and hydroxyferricrocin (HFC) for conidial iron distribution and storage.  TAFC consists of three N(2)-acetyl-N(5)-anhydromevalonyl-N(5)-hydroxyornithine residues cyclically linked by ester bonds; FC is a cyclic hexapeptide with the structure Gly-Ser-Gly-(N(5)-acetyl-N(5)-hydroxyornithine)x3.  The biosynthesis of all four siderophores depends on the hydroxylation of ornithine, catalyzed by the monooxygenase sidA (PubMed:15504822, PubMed:16113265).  Subsequently, the pathways for biosynthesis of extra- and intracellular siderophores split (PubMed:17845073).  For biosynthesis of extracellular siderophores, the transacylase sidF transfers anhydromevalonyl to N(5)-hydroxyornithine (PubMed:17845073).  The required anhydromevalonyl-CoA moiety is derived from mevalonate by CoA ligation and dehydration catalyzed by sidI and sidH respectively (PubMed:22106303).  The acetylation of N(5)-hydroxyornithine for FC biosynthesis involves the constitutively expressed sidL (PubMed:21622789).  FC is hydroxylated to HFC by an as yet uncharacterized enzyme during conidiation (PubMed:17845073).  Assembly of fusarinine C (FsC) and FC is catalyzed by two different nonribosomal peptide synthetases (NRPS), sidD and sidC respectively (PubMed:15953695, PubMed:17845073, PubMed:17464044).  Subsequently, sidG catalyzes N2-acetylation of FsC for forming TAFC (PubMed:17845073).  Both extra- and intracellular siderophores are crucial for growth during iron limitation and virulence (PubMed:16113265).
