Sysname
CDP-ethanolamine:ceramide phosphoethanolaminyltransferase
Reaction(IUBMB)
CDP-ethanolamine + a ceramide = a ceramide phosphorylethanolamine + CMP [RN:
R01503 ]
Reaction(KEGG)
Substrate
Product
ceramide phosphorylethanolamine;
CMP [CPD:
C00055 ]
Comment
The enzyme, studied from the fly Drosophila melanogaster, has homologues among the invertebrates, but not in other animal phyla. Its product, ceramide phosphoethanolamine, is synthesized as the main sphingolipid in cell membranes of arthropods, such as Drosophila and Musca, and is common in worms, bees, spiders, and scorpions. It has also been reported in deep-sea mussels and some sea snails, as well as protozoans and oomycetes. The enzyme requires a Mn(II) cofactor.
