Acyl-[acyl-carrier-protein]--UDP-N-acetylglucosamine O-acyltransferase

Gene

lpxA

Organism
Acidovorax citrulli (strain AAC00-1) (Acidovorax avenae subsp. citrulli)
Status
Reviewed-Annotation score: -Protein inferred from homologyi

Functioni

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

(R)-3-hydroxytetradecanoyl-[acyl-carrier-protein] + UDP-N-acetyl-alpha-D-glucosamine = [acyl-carrier-protein] + UDP-3-O-(3-hydroxytetradecanoyl)-N-acetyl-alpha-D-glucosamine.UniRule annotation

Pathwayi: lipid IV(A) biosynthesis

This protein is involved in step 1 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.
