Function
function
Involved in the modification of the lipid A domain of lipopolysaccharides (LPS). Transfers a phosphate group from undecaprenyl pyrophosphate (C55-PP) to lipid A to form lipid A 1-diphosphate. Contributes to the recycling of undecaprenyl phosphate (C55-P).
Catalytic activity
- an alpha-Kdo-(2->4)-alpha-Kdo-(2->6)-lipid A + di-trans,octa-cis-undecaprenyl diphosphate = an alpha-D-Kdo-(2->4)-alpha-D-Kdo-(2->6)-lipid A 1-diphosphate + di-trans,octa-cis-undecaprenyl phosphate
Pathway
Bacterial outer membrane biogenesis; lipopolysaccharide biosynthesis.
