Chemical Taxonomy | |||||||||||||||||||||||||||||||||||||||||||||||||
Taxonomy Description | This compound belongs to the class of organic compounds known as saccharolipids. These are compounds in which fatty acids are linked directly to a sugar backbone, forming structures that are compatible with membrane bilayers. In the saccharolipids, a sugar substitutes for the glycerol backbone that is present in glycerolipids and glycerophospholipids. The most familiar saccharolipids contain an acylated glucosamine. In contrast to others glycolipids, the fatty acid is not glycosidically linked to the sugar moiety. | ||||||||||||||||||||||||||||||||||||||||||||||||

Enzymes
- General function:
- Involved in biosynthetic process
- Specific function:
- Essential step in lipopolysaccharides biosynthesis. Acts at transfer of 3-deoxy-D-mono octulonic acid (KDO) from CMP-KDO to a tetraacyldisaccharide 1,4'-bisphosphate precursor of lipid A (lipid IVA). Transfers two molecules of KDO to lipid IVA. Degraded by FtsH; therefore FtsH regulates the addition of the sugar moiety of the LPS and thus the maturation of the LPS precursor
- Gene Name:
- waaA
- Locus Tag:
- PA4988
- Molecular weight:
- 46.5 kDa
- General function:
- Involved in transferase activity, transferring pentosyl groups
- Specific function:
- Catalyzes the transfer of the L-Ara4N moiety of the glycolipid undecaprenyl phosphate-alpha-L-Ara4N to lipid A. The modified arabinose is attached to lipid A and is required for resistance to polymyxin and cationic antimicrobial peptides
- Gene Name:
- arnT
- Locus Tag:
- PA3556
- Molecular weight:
- 61.7 kDa
Reactions
4-amino-4-deoxy-alpha-L-arabinopyranosyl di-trans,octa-cis-undecaprenyl phosphate + lipid IV(A) = lipid II(A) + di-trans,octa-cis-undecaprenyl phosphate. |
