Identification
Name:Lipid A export ATP-binding/permease protein msbA
Synonyms:Not Available
Gene Name:msbA
Enzyme Class:Not Available
Biological Properties
General Function:Involved in nucleotide binding
Specific 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
Cellular Location:Cell inner membrane; Multi-pass membrane protein
