General annotation (Comments)

Function	Transfers the gamma-phosphate of ATP to the 4'-position of a tetraacyldisaccharide 1-phosphate intermediate (termed DS-1-P) to form tetraacyldisaccharide 1,4'-bis-phosphate (lipid IVA) By similarity. HAMAP MF_00409
Catalytic activity	ATP + (2-N,3-O-bis(3-hydroxytetradecanoyl)-beta-D-glucosaminyl)-(1->6)-(2-N,3-O-bis(3-hydroxytetradecanoyl)-beta-D-glucosaminyl phosphate) = ADP + (2-N,3-O-bis(3-hydroxytetradecanoyl)-4-O-phosphono-beta-D-glucosaminyl)-(1->6)-(2-N,3-O-bis(3-hydroxytetradecanoyl)-beta-D-glucosaminyl phosphate). HAMAP MF_00409
Pathway	Glycolipid biosynthesis; lipid IV(A) biosynthesis; lipid IV(A) from (3R)-3-hydroxytetradecanoyl-[acyl-carrier-protein] and UDP-N-acetyl-alpha-D-glucosamine: step 6/6. HAMAP MF_00409
Sequence similarities	Belongs to the LpxK family.
