CC -!- FUNCTION: Hydrolyzes the pyrophosphate bond of UDP-2,3-
CC diacylglucosamine to yield 2,3-diacylglucosamine 1-phosphate (lipid X)
CC and UMP by catalyzing the attack of water at the alpha-P atom. Involved
CC in the biosynthesis of lipid A, a phosphorylated glycolipid that
CC anchors the lipopolysaccharide to the outer membrane of the cell.
CC {ECO:0000256|HAMAP-Rule:MF_00575}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=H2O + UDP-2-N,3-O-bis[(3R)-3-hydroxytetradecanoyl]-alpha-D-
CC glucosamine = 2-N,3-O-bis[(3R)-3-hydroxytetradecanoyl]-alpha-D-
CC glucosaminyl 1-phosphate + 2 H(+) + UMP; Xref=Rhea:RHEA:25213,
CC ChEBI:CHEBI:15377, ChEBI:CHEBI:15378, ChEBI:CHEBI:57865,
CC ChEBI:CHEBI:57957, ChEBI:CHEBI:78847; EC=3.6.1.54;
CC Evidence={ECO:0000256|HAMAP-Rule:MF_00575};
CC -!- COFACTOR:
CC Name=Mn(2+); Xref=ChEBI:CHEBI:29035;
CC Evidence={ECO:0000256|HAMAP-Rule:MF_00575};
CC Note=Binds 2 Mn(2+) ions per subunit in a binuclear metal center.
CC {ECO:0000256|HAMAP-Rule:MF_00575};
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 4/6. {ECO:0000256|HAMAP-
CC Rule:MF_00575}.
CC -!- SUBCELLULAR LOCATION: Cell inner membrane {ECO:0000256|HAMAP-
CC Rule:MF_00575}; Peripheral membrane protein {ECO:0000256|HAMAP-
CC Rule:MF_00575}; Cytoplasmic side {ECO:0000256|HAMAP-Rule:MF_00575}.
CC -!- SIMILARITY: Belongs to the LpxH family. {ECO:0000256|HAMAP-
CC Rule:MF_00575}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
