CC   -!- FUNCTION: Catalyzes the hydrolysis of UDP-3-O-myristoyl-N-
CC       acetylglucosamine to form UDP-3-O-myristoylglucosamine and acetate.
CC       Involved in the biosynthesis of lipid A, a phosphorylated glycolipid
CC       that in bacteria anchors the lipopolysaccharide to the outer membrane
CC       of the cell. The target for the lipopolysaccharides produced in the
CC       chloroplast could either be the cell envelope of the eukaryote or the
CC       plastid membrane. {ECO:0000255|HAMAP-Rule:MF_00388}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=a UDP-3-O-[(3R)-3-hydroxyacyl]-N-acetyl-alpha-D-glucosamine +
CC         H2O = a UDP-3-O-[(3R)-3-hydroxyacyl]-alpha-D-glucosamine + acetate;

CC         Evidence={ECO:0000255|HAMAP-Rule:MF_00388};
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 2/6. {ECO:0000255|HAMAP-
CC       Rule:MF_00388}.
CC   -!- SUBCELLULAR LOCATION: Plastid, chloroplast {ECO:0000255|HAMAP-
CC       Rule:MF_00388}.
CC   -!- SIMILARITY: Belongs to the LpxC family. {ECO:0000255|HAMAP-
CC       Rule:MF_00388}.
