CC -!- FUNCTION: Involved in the modification of the lipid A domain of
CC lipopolysaccharides (LPS). Transfers a phosphate group from
CC undecaprenyl pyrophosphate (C55-PP) to lipid A to form lipid A 1-
CC diphosphate. Contributes to the recycling of undecaprenyl phosphate
CC (C55-P). {ECO:0000256|HAMAP-Rule:MF_01945}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=alpha-Kdo-(2->4)-alpha-Kdo-(2->6)-lipid A (E. coli) + di-
CC trans,octa-cis-undecaprenyl diphosphate = (Kdo)2-lipid A 1-
CC diphosphate + di-trans,octa-cis-undecaprenyl phosphate;
CC Xref=Rhea:RHEA:45468, ChEBI:CHEBI:58405, ChEBI:CHEBI:58540,
CC ChEBI:CHEBI:60392, ChEBI:CHEBI:85271; EC=2.7.4.29;
CC Evidence={ECO:0000256|HAMAP-Rule:MF_01945};
CC -!- PATHWAY: Bacterial outer membrane biogenesis; lipopolysaccharide
CC biosynthesis. {ECO:0000256|HAMAP-Rule:MF_01945}.
CC -!- SUBCELLULAR LOCATION: Cell inner membrane {ECO:0000256|HAMAP-
CC Rule:MF_01945}; Multi-pass membrane protein {ECO:0000256|HAMAP-
CC Rule:MF_01945}. Note=Transferase activity takes place on the periplamic
CC side of the inner membrane. {ECO:0000256|HAMAP-Rule:MF_01945}.
CC -!- SIMILARITY: Belongs to the LpxT phosphotransferase family.
CC {ECO:0000256|HAMAP-Rule:MF_01945}.
