Protein

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

Gene

lpxA

Organism
Cyanidium caldarium
Status
Reviewed - Annotation score: 2 out of 5- Protein inferred from homologyi

Functioni

Involved in the biosynthesis of lipid A, a phosphorylated glycolipid that in bacteria anchors the lipopolysaccharide to the outer membrane of the cell. The target for the lipopolysaccharides produced in the chloroplast could either be the cell envelope of the eukaryote or the plastid membrane.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
