In biochemistry, an ether lipid refers to any lipid in which the lipid "tail" group is attached to the glycerol backbone via an ether bond at any position. In contrast, conventional glycerophospholipids and triglycerides are triesters. Structural types include:
In enzymology, a 1-acylglycerol-3-phosphate O-acyltransferase is an enzyme that catalyzes the chemical reaction
In enzymology, an alkylglycerophosphate 2-O-acetyltransferase is an enzyme that catalyzes the chemical reaction
In enzymology, a geranylgeranylglycerol-phosphate geranylgeranyltransferase is an enzyme that catalyzes the chemical reaction
In enzymology, a sn-glycerol-3-phosphate 1-galactosyltransferase is an enzyme that catalyzes the chemical reaction
In enzymology, a 2-C-methyl-D-erythritol 4-phosphate cytidylyltransferase is an enzyme that catalyzes the chemical reaction:
In enzymology, a CDP-diacylglycerol—serine O-phosphatidyltransferase is an enzyme that catalyzes the chemical reaction
In enzymology, a D-ribitol-5-phosphate cytidylyltransferase is an enzyme that catalyzes the chemical reaction
In enzymology, an ethanolamine-phosphate cytidylyltransferase is an enzyme that catalyzes the chemical reaction
In enzymology, a glucose-1-phosphate cytidylyltransferase is an enzyme that catalyzes the chemical reaction
In enzymology, a glycerol-3-phosphate cytidylyltransferase is an enzyme that catalyzes the chemical reaction
Archaeol is a diether composed of two phytanyl chains linked to the sn-2 and sn-3 positions of glycerol. As its phosphate ester, it is a common component of the membranes of archaea.
sn-Glycerol 1-phosphate is the conjugate base of a phosphoric ester of glycerol. It is a component of ether lipids, which are common for archaea.
Glycerol-3-phosphate 2-O-acyltransferase is an enzyme with systematic name acyl-CoA:sn-glycerol 3-phosphate 2-O-acyltransferase. This enzyme catalyses the following chemical reaction
Geranylfarnesyl diphosphate synthase is an enzyme with systematic name geranylgeranyl-diphosphate:isopentenyl-diphosphate transtransferase . This enzyme catalyses the following chemical reaction
Diacylglycerol kinase (CTP dependent) (EC 2.7.1.174, DAG kinase, CTP-dependent diacylglycerol kinase, diglyceride kinase) is an enzyme with systematic name CTP:1,2-diacyl-sn-glycerol 3-phosphotransferase. This enzyme catalyses the following chemical reaction
1L-myo-inositol 1-phosphate cytidylyltransferase is an enzyme with systematic name CTP:1L-myo-inositol 1-phosphate cytidylyltransferase. This enzyme catalyses the following chemical reaction
Pseudaminic acid cytidylyltransferase is an enzyme with systematic name CTP:5,7-diacetamido-3,5,7,9-tetradeoxy-L-glycero-alpha-L-manno-nonulosonic acid cytidylyltransferase. This enzyme catalyses the following chemical reaction
CDP-L-myo-inositol myo-inositolphosphotransferase is an enzyme with systematic name CDP-1L-myo-inositol:1L-myo-inositol 1-phosphate myo-inositolphosphotransferase. This enzyme catalyses the following chemical reaction
Hydroxyarchaeol is a core lipid unique to archaea, similar to archaeol, with a hydroxide functional group at the carbon-3 position of one of its ether side chains. It is found exclusively in certain taxa of methanogenic archaea, and is a common biomarker for methanogenesis and methane-oxidation. Isotopic analysis of hydroxyarchaeol can be informative about the environment and substrates for methanogenesis.
