Dolichol-phosphate
Dolichol monophosphate is a fatty alcohol Fatty alcohols (or long-chain alcohols) are usually high-molecular-weight, straight-chain primary alcohols, but can also range from as few as 4–6 carbons to as many as 22–26, derived from natural fats and oils. The precise chain length varies .... See also * Dolichyl-phosphatase * Dolichyl-phosphate beta-D-mannosyltransferase * DPM1 Organophosphates {{organic-compound-stub ...

DPM1
Dolichol-phosphate mannosyltransferase is an enzyme that in humans is encoded by the ''DPM1'' gene. Function Dolichol-phosphate mannose (Dol-P-Man) serves as a donor of mannosyl residues on the lumenal side of the endoplasmic reticulum (ER). Lack of Dol-P-Man results in defective surface expression of GPI-anchored proteins. Dol-P-Man is synthesized from GDP-mannose and dolichol-phosphate on the cytosolic side of the ER by the enzyme dolichyl-phosphate mannosyltransferase. Human DPM1 lacks a carboxy-terminal transmembrane domain and signal sequence and is regulated by DPM2. Model organisms Model organisms have been used in the study of DPM1 function. A conditional knockout mouse line called ''Dpm1tm1b(KOMP)Wtsi'' was generated at the Wellcome Trust Sanger Institute. Male and female animals underwent a standardized phenotypic screen In genetics, the phenotype () is the set of observable characteristics or traits of an organism. The term covers the organism's morpholo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fatty Alcohol
Fatty alcohols (or long-chain alcohols) are usually high-molecular-weight, straight-chain primary alcohols, but can also range from as few as 4–6 carbons to as many as 22–26, derived from natural fats and oils. The precise chain length varies with the source. Some commercially important fatty alcohols are lauryl, stearyl, and oleyl alcohols. They are colourless oily liquids (for smaller carbon numbers) or waxy solids, although impure samples may appear yellow. Fatty alcohols usually have an even number of carbon atoms and a single alcohol group (–OH) attached to the terminal carbon. Some are unsaturated and some are branched. They are widely used in industry. As with fatty acids, they are often referred to generically by the number of carbon atoms in the molecule, such as "a C12 alcohol", that is an alcohol having 12 carbons, for example dodecanol. Production and occurrence Most fatty alcohols in nature are found as waxes which are esters of fatty acids and fatty alcohols. T ...

Dolichyl-phosphatase
The enzyme dolichyl-phosphatase (EC 3.1.3.51) catalyzes the reaction :dolichyl phosphate + H2O \rightleftharpoons dolichol + phosphate This enzyme belongs to the family of hydrolases, to be specific, those acting on phosphoric monoester bonds. The systematic name A systematic name is a name given in a systematic way to one unique group, organism, object or chemical substance, out of a specific population or collection. Systematic names are usually part of a nomenclature. A semisystematic name or semitrivial ... is dolichyl-phosphate phosphohydrolase. Other names in common use include dolichol phosphate phosphatase, dolichol phosphatase, dolichol monophosphatase, dolichyl monophosphate phosphatase, dolichyl phosphate phosphatase, polyisoprenyl phosphate phosphatase, polyprenylphosphate phosphatase, and Dol-''P'' phosphatase. This enzyme participates in ''N''-linked-glycan biosynthesis. References * * * EC 3.1.3 Enzymes of unknown structure {{3.1-enzyme-stub ...

Dolichyl-phosphate Beta-D-mannosyltransferase
In enzymology, a dolichyl-phosphate beta-D-mannosyltransferase () is an enzyme that catalyzes the chemical reaction :GDP-mannose + dolichyl phosphate \rightleftharpoons GDP + dolichyl D-mannosyl phosphate Thus, the two substrates of this enzyme are GDP-mannose and dolichyl phosphate, whereas its two products are GDP and dolichyl D-mannosyl phosphate. This enzyme belongs to the family of glycosyltransferases, specifically the hexosyltransferases. The systematic name A systematic name is a name given in a systematic way to one unique group, organism, object or chemical substance, out of a specific population or collection. Systematic names are usually part of a nomenclature. A semisystematic name or semitrivial ... of this enzyme class is GDP-mannose:dolichyl-phosphate beta-D-mannosyltransferase. Other names in common use include GDP-Man:DolP mannosyltransferase, dolichyl mannosyl phosphate synthase, dolichyl-phospho-mannose synthase, GDP-mannose:dolichyl-phosphate mannosyltran ...
