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)

Apoptosis in HIV-1-infected CD4+ primary T cells is triggered by the alteration of the PI3K and p53 pathways, which converge on the FOXO3a transcriptional activator. Tat alone can cause activation of FOXO3a and of its proapoptotic target genes. To understand
