Protein

Lipid A export ATP-binding/permease protein MsbA

Gene

msbA

Organism
Burkholderia pseudomallei (strain 1710b)
Status
Reviewed-Annotation score: Annotation score: 3 out of 5-Protein inferred from homologyi

Functioni

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.
