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:0000255|HAMAP-Rule:MF_00409}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=ATP + {2-N,3-O-bis[(3R)-3-hydroxytetradecanoyl]-beta-D-
CC         glucosaminyl}-(1->6)-{2-N,3-O-bis[(3R)-3-hydroxytetradecanoyl]-alpha-
CC         D-glucosaminyl phosphate} = ADP + {2-N,3-O-bis[(3R)-3-
CC         hydroxytetradecanoyl]-4-O-phospho-beta-D-glucosaminyl}-(1->6)-{2-N,3-
CC         O-bis[(3R)-3-hydroxytetradecanoyl]-alpha-D-glucosaminyl phosphate}.;
CC         EC=2.7.1.130; Evidence={ECO:0000255|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:0000255|HAMAP-
CC       Rule:MF_00409}.
CC   -!- SIMILARITY: Belongs to the LpxK family. {ECO:0000255|HAMAP-
CC       Rule:MF_00409}.
