Protein

UDP-2,3-diacylglucosamine hydrolase

Gene

lpxH

Organism
Shewanella putrefaciens (strain CN-32 / ATCC BAA-453)
Status
Reviewed-Annotation score: Annotation score: 3 out of 5-Protein inferred from homologyi

Functioni

Hydrolyzes the pyrophosphate bond of UDP-2,3-diacylglucosamine to yield 2,3-diacylglucosamine 1-phosphate (lipid X) and UMP by catalyzing the attack of water at the alpha-P atom. Involved in the biosynthesis of lipid A, a phosphorylated glycolipid that anchors the lipopolysaccharide to the outer membrane of the cell.UniRule annotation

Catalytic activityi

UDP-2-N,3-O-bis((3R)-3-hydroxytetradecanoyl)-alpha-D-glucosamine + H2O = 2-N,3-O-bis((3R)-3-hydroxytetradecanoyl)-alpha-D-glucosaminyl 1-phosphate + UMP.UniRule annotation

Cofactori

Mn2+UniRule annotationNote: Binds 2 Mn2+ ions per subunit in a binuclear metal center.UniRule annotation

Pathwayi: lipid IV(A) biosynthesis

This protein is involved in step 4 of the subpathway that synthesizes lipid IV(A) from (3R)-3-hydroxytetradecanoyl-[acyl-carrier-protein] and UDP-N-acetyl-alpha-D-glucosamine.UniRule annotation
Proteins known to be involved in the 6 steps of the subpathway in this organism are:
  1. Acyl-[acyl-carrier-protein]--UDP-N-acetylglucosamine O-acyltransferase (lpxA)
  2. UDP-3-O-acyl-N-acetylglucosamine deacetylase (lpxC)
  3. no protein annotated in this organism
  4. UDP-2,3-diacylglucosamine hydrolase (lpxH)
  5. Lipid-A-disaccharide synthase (lpxB)
  6. Tetraacyldisaccharide 4'-kinase (lpxK)
This subpathway is part of the pathway lipid IV(A) biosynthesis, which is itself part of Glycolipid biosynthesis.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes lipid IV(A) from (3R)-3-hydroxytetradecanoyl-[acyl-carrier-protein] and UDP-N-acetyl-alpha-D-glucosamine, the pathway lipid IV(A) biosynthesis and in Glycolipid biosynthesis.
