Identification
Name:KDO(2)-lipid IV(A) with laurate
DescriptionKDO(2)-lipid IV(a) is a saccharolipid. The most familiar saccharolipids are the acylated glucosamine precursors of the lipid A component of the lipopolysaccharides in Gram-negative bacteria. Typical lipid A molecules are disaccharides of glucosamine, which are derivatized with as many as seven fatty-acyl chains. The minimal lipopolysaccharide required for growth in E. coli is Kdo2-Lipid A, a hexa-acylated disaccharide of glucosamine that is glycosylated with two 3-deoxy-D-manno-octulosonic acid (Kdo) residues.

Enzymes

General function:
Involved in transferase activity, transferring acyl groups
Specific function:
Acylates the intermediate (KDO)2-lipid IVA to form (KDO)2-(lauroyl)-lipid IVA. Has 10 fold selectivity for lauroyl- ACP over myristoyl-ACP
Gene Name:
htrB
Uniprot ID:
P0ACV0
Molecular weight:
35407
General function:
Involved in transferase activity, transferring acyl groups
Specific function:
Transfers myristate or laurate, activated on ACP, to the lipid IVA moiety of (KDO)2-(lauroyl)-lipid IVA. Decanoyl, palmitoyl, palmitoleoyl, and (R)-3-hydroxymyristoyl-ACP are poor acyl donors. Functions optimally after laurate incorporation by htrB has taken place. Acylates (KDO)2-(lauroyl)-lipid IVA about 100 times faster than (KDO)2-lipid IVA. Displays a preference for myristoyl-ACP over lauroyl-ACP
