Status
Reviewed-Annotation score: Annotation score: 2 out of 5-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

Pathway:ilipid 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. 3-hydroxyacyl-[acyl-carrier-protein] dehydratase FabZ (Cpar_0528)
  3. no protein annotated in this organism
  4. no protein annotated in this organism
  5. no protein annotated in this organism
  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.

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into Uniref entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
