Identification
Name: Lipopolysaccharide export system protein lptA
Synonyms: Not Available
Gene Name: lptA
Enzyme Class: Not Available
Biological Properties
General Function: Involved in lipopolysaccharide binding
Specific Function: Required for the translocation of lipopolysaccharide (LPS) from the inner membrane to the outer membrane. May act as a chaperone that facilitates LPS transfer across the aquaeous environment of the periplasm. Interacts specifically with the lipid A domain of LPS
Cellular Location: Periplasm
