<span class="mw-page-title-main">Saccharolipid</span> Class of chemical compounds

Saccharolipids are chemical compounds containing fatty acids linked directly to a sugar backbone, forming structures that are compatible with membrane bilayers. In the saccharolipids, a monosaccharide substitutes for the glycerol backbone present in glycerolipids and glycerophospholipids. 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 Escherichia coli is Kdo2-Lipid A, a hexa-acylated disaccharide of glucosamine (LipidA) that is glycosylated with two 3-deoxy-D-manno-octulosonic acid (Kdo) residues.

<span class="mw-page-title-main">Haloacid dehydrogenase superfamily</span>

The haloacid dehydrogenase superfamily is a superfamily of enzymes that include phosphatases, phosphonatases, P-type ATPases, beta-phosphoglucomutases, phosphomannomutases, and dehalogenases, and are involved in a variety of cellular processes ranging from amino acid biosynthesis to detoxification.

In molecular biology, the lipopolysaccharide kinase (Kdo/WaaP) family is a family of lipopolysaccharide kinases that includes lipopolysaccharide core heptose(I) kinase rfaP. Lipopolysaccharide core heptose(I) kinase rfaP is required for the addition of phosphate to O-4 of the first heptose residue of the lipopolysaccharide (LPS) inner core region. It has previously been shown that it is necessary for resistance to hydrophobic and polycationic antimicrobials in E. coli and that it is required for virulence in invasive strains of Salmonella enterica. The family also includes 3-deoxy-D-manno-octulosonic acid kinase from Haemophilus influenzae, which phosphorylates Kdo-lipid IV(A), a lipopolysaccharide precursor, and is involved in virulence.

<span class="mw-page-title-main">DAHP synthase</span> Class of enzymes

3-Deoxy-D-arabinoheptulosonate 7-phosphate (DAHP) synthase is the first enzyme in a series of metabolic reactions known as the shikimate pathway, which is responsible for the biosynthesis of the amino acids phenylalanine, tyrosine, and tryptophan. Since it is the first enzyme in the shikimate pathway, it controls the amount of carbon entering the pathway. Enzyme inhibition is the primary method of regulating the amount of carbon entering the pathway. Forms of this enzyme differ between organisms, but can be considered DAHP synthase based upon the reaction that is catalyzed by this enzyme.
