Protein Family Models

This family of proteins are involved in lipopolysaccharide transport across the gram negative inner and outer membranes. The type examples for this family are E. coli LptA Swiss:P0ADV1 and the N-terminal domain of LptD Swiss:P31554. [1]. 18424520.

lipopolysaccharide ABC transporter substrate-binding protein LptA plays a role in the delivery of lipopolysaccharide to the outer leaflet of the outer membrane

Members of this protein family include LptA (previously called YhbN). It was shown to be an essential protein in E. coli, implicated in cell envelope integrity, and to play a role in the delivery of LPS to the outer leaflet of the outer membrane. It works with LptB (formerly yhbG), a homolog of ABC transporter ATP-binding proteins, encoded by an adjacent gene. Numerous homologs in other Proteobacteria are found in a conserved location near lipopolysaccharide inner core biosynthesis genes. This family is related to organic solvent tolerance protein (OstA), though distantly.
