FunFam 272: Lipid A export ATP-binding/permease protein MsbA

There are 1 EC terms in this cluster

Please note: EC annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

Note: The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.

EC Term Annotations Evidence
ABC-type lipid A-core oligosaccharide transporter. [EC: 7.5.2.6]
ATP + H(2)O + lipid A-core oligosaccharide(Side 1) = ADP + phosphate + lipid A-core oligosaccharide(Side 2).
  • An ATP-binding cassette (ABC) type transporter, characterized by the presence of two similar ATP-binding domains/proteins and two integral membrane domains/proteins.
  • The enzyme, best characterized from the bacterium Escherichia coli, is located in the inner membrane and mediates the movement of lipid A attached to the core oligosaccharide from the cytoplasm to the periplasmic side of the inner membrane, an important step in the lipopolysaccharide biosynthetic pathway.
  • Not to be confused with EC 7.5.2.5, which is implicated in the translocation of LPS from the inner membrane to the outer membrane and acts later in the process.
