[Glycolipids of the cell surface--biochemistry of their decomposition].
Glycosphingolipids (GSL) form cell-type-specific patterns on the surface of eukaryotic cells. For the maintenance of these patterns, biosynthesis, intracellular transport, and degradation of GSL are thought to proceed in a coordinated fashion. After transport from the plasma membrane to the lysosomes the degradation of GSL requires protein cofactors to solubilize the membrane-bound substrates of the degradative enzymes. Inborn errors of metabolism leading to defective hydrolases or activator proteins give rise to sphingolipid storage diseases; in some cases the residual enzyme activity can be correlated with the clinical manifestations.
