Description
The enzyme catalyses a step of lipid A biosynthesis. LpxD from Escherichia prefers (R,S)-3-hydroxytetradecanoyl-[acyl-carrier protein] over (R,S)-3-hydroxyhexadecanoyl-[acyl-carrier protein]. Escherichia coli lipid A acyltransferases do not have an absolute specificity for 14-carbon hydroxy fatty acids but can transfer fatty acids differing by one carbon unit if the fatty acid substrates are available. When grown on 1% propionic acid, lipid A also contains the odd-chain fatty acids tridecanoic acid, pentadecanoic acid, hydroxytridecanoic acid, and hydroxypentadecanoic acid.

Synonyms
UDP-3-O-acyl-glucosamine N-acyltransferase; UDP-3-O-(R-3-hydroxymyristoyl)-glucosamine N-acyltransferase; acyltransferase LpxD; acyl-ACP:UDP-3-O-(3-hydroxyacyl)-GlcN N-acyltransferase; firA (gene name); lpxD (gene name); (3R)-3-hydroxymyristoyl-[acyl-carrier protein]:UDP-3-O-[(3R)-3-hydroxymyristoyl]-α-D-glucosamine N-acetyltransferase
Reaction
(3R)-3-hydroxytetradecanoyl-[acyl-carrier protein] + UDP-3-O-[(3R)-3-hydroxytetradecanoyl]-α-D-glucosamine = UDP-2-N,3-O-bis[(3R)-3-hydroxytetradecanoyl]-α-D-glucosamine + a holo-[acyl-carrier protein]
