CC -!- FUNCTION: Part of the ABC transporter complex IrtAB involved in the
CC import of iron-bound mycobactin (Fe-MBT) and carboxymycobactin (Fe-
CC cMBT). Mycobactins are then reduced by the siderophore interaction
CC domain to facilitate iron release in the bacterial cell. Transmembrane
CC domains (TMD) form a pore in the membrane and the ATP-binding domain
CC (NBD) is responsible for energy generation.
CC {ECO:0000250|UniProtKB:G7CBF5}.
CC -!- COFACTOR:
CC Name=FAD; Xref=ChEBI:CHEBI:57692;
CC Evidence={ECO:0000250|UniProtKB:G7CBF5};
CC -!- SUBUNIT: Forms a heterodimer with IrtB. {ECO:0000250|UniProtKB:G7CBF5}.
CC -!- SUBCELLULAR LOCATION: Cell inner membrane
CC {ECO:0000250|UniProtKB:G7CBF5}; Multi-pass membrane protein
CC {ECO:0000250|UniProtKB:G7CBF5}.
CC -!- DOMAIN: In IrtA the ATP-binding domain (NBD) and the transmembrane
CC domain (TMD) are fused. In addition, IrtA contains an N-terminal
CC siderophore interaction domain (SID) that binds FAD.
CC {ECO:0000250|UniProtKB:G7CBF5}.
CC -!- SIMILARITY: Belongs to the ABC transporter superfamily. Siderophore-
CC Fe(3+) uptake transporter (SIUT) (TC 3.A.1.21) family. {ECO:0000305}.
