Glycosylphosphatidylinositol (GPI) anchor biosynthesis takes place in the endoplasmic reticulum (ER). After protein attachment, the GPI anchor is transported to the Golgi where it undergoes fatty acid remodeling. The ER exit of GPI-anchored proteins is controlled by glycan remodeling and

Ceramides (Cer) and cerebrosides are important sphingolipids (SL) involved in many biological processes. Herein, the SL content of yellow lupin seeds (Lupinus luteus) was determined by liquid-liquid extraction, mild alkaline hydrolysis (1 h at 37 °C) and reversed-phase liquid chromatography with negative

Sphingolipids have been demonstrated to be involved in many human diseases. However, measurement of sphingolipids, especially of sphingosine 1-phosphate (S1P) and dihydro-sphingosine 1-phosphate (dhS1P), in blood samples requires strict sampling, since blood cells easily secrete these substances during sampling and

Metabolic highways may be orchestrated by the assembly of sequential enzymes into protein complexes, or metabolons, to facilitate efficient channeling of intermediates and to prevent undesired metabolic cross-talk while maintaining metabolic flexibility. Here we report the isolation of the dynamic
