CC   -!- FUNCTION: Catalyzes the hydrolysis of UDP-3-O-myristoyl-N-
CC       acetylglucosamine to form UDP-3-O-myristoylglucosamine and acetate, the
CC       committed step in lipid A biosynthesis. {ECO:0000255|HAMAP-
CC       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         ChEBI:CHEBI:137740, ChEBI:CHEBI:173225; EC=3.5.1.108;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_00388};
CC   -!- COFACTOR:
CC       Name=Zn(2+); Xref=ChEBI:CHEBI:29105;
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   -!- SIMILARITY: Belongs to the LpxC family. {ECO:0000255|HAMAP-
CC       Rule:MF_00388}.
