General description
Sphingolipid Ceramide N-Deacylase from Pseudomonas sp. is a hydrolytic enzyme.
Application
Sphingolipid Ceramide N-Deacylase from Pseudomonas sp. has been used in enzymatic conversion and derivatization of sulfatides. It has also been used to hydrolyze the fatty acid chain of mactosyl ceramide.
Biochem/physiol Actions
Sphingolipid Ceramide N-Deacylase from Pseudomonas sp., under certain conditions, can recyclate lyso-sphingolipids. It condenses fatty acids to sphingosine to generate ceramide. The enzyme mainly acts on neutral and acidic glycosphingolipids.
Hydrolyzes the N-acyl linkage between fatty acids and sphingosines in ceramides of various sphingolipids.
Unit Definition
One unit will hydrolyze 1 μmol of asialo GM1 per minute at pH 6.0 at 37 °C.
Physical form
Solution in 50 mM sodium acetate, pH 6.0, with 0.1% Lubrol PX.

Sphingolipid ceramide N-deacylase (SCDase, EC 3.5.1.69) is a hydrolytic enzyme isolated from Pseudomonas sp. TK 4. In addition to its primary deacylation function, this enzyme is able to reacylate lyso-sphingolipids under specific conditions. We immobilised this enzyme on magnetic macroporous

Glycosphingolipids (GSLs) have been implicated as playing major roles in cellular interactions and control of cell proliferation in muticellular organisms. Moreover GSLs and other sphingolipids such as sphingomyelins, ceramides and sphingosines serve a variety of roles in signal transduction. Hence
A novel enzyme that cleaves the N-acyl linkage of ceramides in various glycosphingolipids as well as sphingomyelin to produce their lyso forms.
