ENZYME entry: EC 7.5.2.6

Accepted Name
ABC-type lipid A-core oligosaccharide transporter.
Alternative Name(s)
ATP-dependent lipid A-core flippase.
Lipid flippase.
Reaction catalysed
ATP + H(2)O + lipid A-core oligosaccharide(Side 1) <=> ADP + phosphate + lipid A-core oligosaccharide(Side 2)
Comment(s)
  • 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.
