Protein

UDP-3-O-acyl-N-acetylglucosamine deacetylase

Gene

lpxC

Organism
Aquifex aeolicus (strain VF5)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

Catalyzes the hydrolysis of UDP-3-O-myristoyl-N-acetylglucosamine to form UDP-3-O-myristoylglucosamine and acetate, the committed step in lipid A biosynthesis.UniRule annotation1 Publication

Catalytic activityi

UDP-3-O-((3R)-3-hydroxytetradecanoyl)-N-acetyl-alpha-D-glucosamine + H2O = UDP-3-O-((3R)-3-hydroxytetradecanoyl)-alpha-D-glucosamine + acetate.UniRule annotation2 Publications

Zn2+UniRule annotation1 Publication

Pathwayi: lipid IV(A) biosynthesis

This protein is involved in step 2 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. no protein annotated in this organism
  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.
