CC -!- FUNCTION: Involved in the biosynthesis of lipid A, a phosphorylated
CC glycolipid that in bacteria anchors the lipopolysaccharide to the outer
CC membrane of the cell. Lipid A-like molecules in plants may serve as
CC structural components of the outer membranes of mitochondria and/or
CC chloroplasts, or may be involved in signal transduction or plant
CC defense responses (Potential). {ECO:0000305}.
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 Xref=Rhea:RHEA:67816, ChEBI:CHEBI:15377, ChEBI:CHEBI:30089,
CC ChEBI:CHEBI:137740, ChEBI:CHEBI:173225; EC=3.5.1.108;
CC Evidence={ECO:0000250|UniProtKB:P0A725};
CC -!- COFACTOR:
CC Name=Zn(2+); Xref=ChEBI:CHEBI:29105;
CC Evidence={ECO:0000250|UniProtKB:P0A725};
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:0000269|PubMed:21709257}.
CC -!- SUBCELLULAR LOCATION: Mitochondrion {ECO:0000269|PubMed:21709257,
CC ECO:0000305|PubMed:25732537}.
CC -!- MISCELLANEOUS: Plants silencing LPXC do not have altered morphology
CC compared to wild-type plants when grown under normal growth conditions,
CC but they do not accumulate 2,3-diacylglucosamine-1-phosphate.
CC {ECO:0000305|PubMed:21709257}.
CC -!- SIMILARITY: Belongs to the LpxC family. {ECO:0000305}.
CC -!- SEQUENCE CAUTION:
CC Sequence=AAG03126.1; Type=Erroneous gene model prediction; Note=The predicted gene has been split into 2 genes: At1g24880 and At1g24881.; Evidence={ECO:0000305};
