>gnl|CDD|100042 cd03351, LbH_UDP-GlcNAc_AT, UDP-N-acetylglucosamine O-acyltransferase (UDP-GlcNAc acyltransferase): Proteins in this family catalyze the transfer of (R)-3-hydroxymyristic acid from its acyl carrier protein thioester to UDP-GlcNAc. It is the first enzyme in the lipid A biosynthetic pathway and is also referred to as LpxA. Lipid A is essential for the growth of Escherichia coli and related bacteria. It is also essential for maintaining the integrity of the outer membrane. UDP-GlcNAc acyltransferase is a homotrimer of left-handed parallel beta helix (LbH) subunits. Each subunit contains an N-terminal LbH region with 9 turns, each containing three imperfect tandem repeats of a hexapeptide repeat motif (X-[STAV]-X-[LIV]-[GAED]-X), and a C-terminal alpha-helical region..
