FUNCTION:Involved in lipid A export and possibly also in glycerophospholipid export and for biogenesis of the outer membrane. Transmembrane domains (TMD) form a pore in the inner membrane and the ATP-binding domain (NBD) is responsible for energy generation.
SUBUNIT:Homodimer.
SUBCELLULAR LOCATION:Integral membrane protein. Inner membrane.
DOMAIN:In msbA the ATP-binding domain (NBD) and the transmembrane domain (TMD) are fused.
SIMILARITY:Belongs to the ABC transporter family. Lipid exporter (TC 3.A.1.106) subfamily.
