>TIGR02207 lipid_A_htrB lipid A biosynthesis lauroyl (or palmitoleoyl) acyltransferase; InterPro: IPR011920 Bacterial lipopolysachharides (LPS) are glycolipids that make up the outer monolayer of the outer membranes of most Gram-negative bacteria. Though LPS moleculesare variable, they all show the same general features: an outer polysaccharide which is attached to the lipid component, termed lipid A . The polysaccharide component consists of a variable repeat-structure polysaccharide known as the O-antigen, and a highly conserved short core oligosaccharide which connects the O-antigen to lipid A. Lipid A is a glucosamine-based phospholipid that makes up the membrane anchor region of LPS . The structure of lipid A is relatively invariant between species, presumably reflecting its fundamental role in membrane integrity. Recognition of lipid A by the innate immune system can lead to a response even at picomolar levels. In some genera, such as Neisseria and Haemophilus, lipooligosaccharides (LOS) are the predominant glycolipids . These are analogous to LPS except that they lack O-antigens, with the LOS oligosaccharide structures limited to 10 saccharide units. This entry represents a narrow clade of acyltransferases, nearly all of which transfer a lauroyl group to KDO2-lipid IV-A, a lipid A precursor; these proteins are termed lipid A biosynthesis lauroyl acyltransferase, HtrB. An exception is a closely related paralog of Escherichia coli HtrB, LpxP, which acts in cold shock conditions by transferring a palmitoleoyl rather than lauroyl group to the lipid A precursor. Members of this family are homologous to the family of acyltransferases responsible for the next step in lipid A biosynthesis .; GO: 0016747 transferase activity transferring groups other than amino-acyl groups, 0009276 1-2nm peptidoglycan-based cell wall, 0016021 integral to membrane.
