Description

General description

Sphingolipid ceramide N-deacylase (SCDase) is a native sphingolipid ceramide N-deacylase from Pseudomonas species. It hydrolyzes the N-acyl linkage between fatty acids and the sphingosine base of ceramide in several sphingolipids and gangliosides. This enzyme catalyzes the condensation reaction between fatty acids and sphingosine bases and forms sphingolipids. It is also involved in transacylation reactions. SCDase is not recommended for hydrolysis of ceramide. It is also used to prepare lysoglycosphingolipids (lysoGSLs) effortlessly.

Application

Sphingolipid ceramide N-Deacylase, Pseudomonas sp. has been used as a PP2A enhancer to study its effects on phosphatase and tensin homolog (PTEN) in forkhead box O3 (FOXO3a) phosphorylation in primary CD4⁺ T cells.

Warning

Toxicity: Standard Handling (A)
