Comments [?]

Function Catalyzes the transfer of myristate from myristoyl-acyl carrier protein (ACP) to Kdo(2)-(lauroyl)-lipid IV(A) to form Kdo(2)-lipid A.
Catalytic activity RHEA:28438: dodecanoyl-(Kdo)2-lipid IVA + tetradecanoyl-[ACP] = alpha-Kdo-(2->4)-alpha-Kdo-(2->6)-lipid A + holo-[ACP]
EC 2.3.1.243
Pathway Glycolipid biosynthesis; KDO(2)-lipid A biosynthesis; KDO(2)-lipid A from CMP-3-deoxy-D-manno-octulosonate and lipid IV(A): step 4/4.
Bacterial outer membrane biogenesis; lipopolysaccharide biosynthesis.
Subcellular location Cell inner membrane; Single-pass membrane protein.
Similarity Belongs to the LpxL/LpxM/LpxP family. LpxM subfamily.
