WebThe Role of Phospholipase D Enzyme(s) in Modulating Cell Signaling: Implications for Cancer Drug Development Sphingolipids are a class of lipids containing a backbone of sphingoid bases, a set of aliphatic amino alcohols that includes sphingosine. They were discovered in brain extracts in the 1870s and were named after the mythological sphinx because of their enigmatic nature. These compounds play important roles in signal transduction and cell recognition. Sphingolipidoses, or disorders of sphin…

Web1 Theory NTP hydrolysis is a simple chemical reaction involving the cleavage of the β–γ phosphodiester bond to yield NDP (nucleoside diphosphate) and inorganic phosphate (P i) ( Fig. 25.1). Enzymes that catalyze this reaction are referred to as Nucleoside Triphosphate Hydrolases or simply NTPases. WebIn enzymology, a sphingosine cholinephosphotransferase (EC 2.7.8.10) is an enzyme that catalyzes the chemical reaction. CDP-choline + sphingosine CMP + sphingosyl-phosphocholine. Thus, the two substrates of this enzyme are CDP-choline and sphingosine, whereas its two products are CMP and sphingosyl-phosphocholine.. This enzyme belongs …
