Organism
Methylibium petroleiphilum (strain ATCC BAA-1232 / LMG 22953 / PM1)
Status
Functioni
Transfers the gamma-phosphate of ATP to the 4'-position of a tetraacyldisaccharide 1-phosphate intermediate (termed DS-1-P) to form tetraacyldisaccharide 1,4'-bis-phosphate (lipid IVA).UniRule annotation
Catalytic activityi
- ATP + (2-N,3-O-bis((3R)-3-hydroxytetradecanoyl)-beta-D-glucosaminyl)-(1->6)-(2-N,3-O-bis((3R)-3-hydroxytetradecanoyl)-alpha-D-glucosaminyl phosphate) = ADP + (2-N,3-O-bis((3R)-3-hydroxytetradecanoyl)-4-O-phospho-beta-D-glucosaminyl)-(1->6)-(2-N,3-O-bis((3R)-3-hydroxytetradecanoyl)-alpha-D-glucosaminyl phosphate).UniRule annotation EC:2.7.1.130
: lipid IV(A) biosynthesis Pathwayi
This protein is involved in step 6 of the subpathway that synthesizes lipid IV(A) from (3R)-3-hydroxytetradecanoyl-[acyl-carrier-protein] and UDP-N-acetyl-alpha-D-glucosamine.UniRule annotationProteins known to be involved in the 6 steps of the subpathway in this organism are:
- Acyl-[acyl-carrier-protein]--UDP-N-acetylglucosamine O-acyltransferase (lpxA)
- UDP-3-O-acyl-N-acetylglucosamine deacetylase (lpxC)
- no protein annotated in this organism
- UDP-2,3-diacylglucosamine hydrolase (lpxH)
- Lipid-A-disaccharide synthase (lpxB)
- Tetraacyldisaccharide 4'-kinase (lpxK)
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.
