CC -!- FUNCTION: Transfers the gamma-phosphate of ATP to the 4'-position of a
CC tetraacyldisaccharide 1-phosphate intermediate (termed DS-1-P) to form
CC tetraacyldisaccharide 1,4'-bis-phosphate (lipid IVA).
CC {ECO:0000256|ARBA:ARBA00002274, ECO:0000256|HAMAP-Rule:MF_00409}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=a lipid A disaccharide + ATP = a lipid IVA + ADP + H(+);
CC Xref=Rhea:RHEA:67840, ChEBI:CHEBI:15378, ChEBI:CHEBI:30616,
CC ChEBI:CHEBI:176343, ChEBI:CHEBI:176425, ChEBI:CHEBI:456216;
CC EC=2.7.1.130; Evidence={ECO:0000256|HAMAP-Rule:MF_00409};
CC -!- PATHWAY: Glycolipid biosynthesis; lipid IV(A) biosynthesis; lipid IV(A)
CC from (3R)-3-hydroxytetradecanoyl-[acyl-carrier-protein] and UDP-N-
CC acetyl-alpha-D-glucosamine: step 6/6. {ECO:0000256|ARBA:ARBA00004870,
CC ECO:0000256|HAMAP-Rule:MF_00409}.
CC -!- SIMILARITY: Belongs to the LpxK family. {ECO:0000256|HAMAP-
CC Rule:MF_00409}.
