RT Strain).";
RL Submitted (MAR-2006) to the EMBL/GenBank/DDBJ databases.
CC -!- FUNCTION: Involved in lipopolysaccharide (LPS) biosynthesis.
CC Translocates lipid A-core from the inner to the outer leaflet of the
CC inner membrane. Transmembrane domains (TMD) form a pore in the inner
CC membrane and the ATP-binding domain (NBD) is responsible for energy
CC generation. {ECO:0000255|HAMAP-Rule:MF_01703}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=ATP + H2O + lipid A-core oligosaccharideSide 1 = ADP +
CC phosphate + lipid A-core oligosaccharideSide 2.; EC=7.5.2.6;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_01703};
CC -!- SUBUNIT: Homodimer. {ECO:0000255|HAMAP-Rule:MF_01703}.
CC -!- SUBCELLULAR LOCATION: Cell inner membrane {ECO:0000255|HAMAP-
CC Rule:MF_01703}; Multi-pass membrane protein {ECO:0000255|HAMAP-
CC Rule:MF_01703}.
CC -!- DOMAIN: In MsbA the ATP-binding domain (NBD) and the transmembrane
CC domain (TMD) are fused. {ECO:0000255|HAMAP-Rule:MF_01703}.
CC -!- SIMILARITY: Belongs to the ABC transporter superfamily. Lipid exporter
CC (TC 3.A.1.106) family. {ECO:0000255|HAMAP-Rule:MF_01703}.
