Sphingolipid Hydrolysis: Sphingolipid Ceramide N-Deacylase (SCDase)

Sphingolipid ceramide N-deacylase (SCDase) is derived from Pseudomonas and hydrolyzes the N-acyl linkage between fatty acids and sphingosine bases in ceramides of various sphingolipids. The enzyme also catalyzes the reverse reaction and possesses transacylation activity. SCDase acts on various acidic and neutral glycosphingolipids and sphingomyelin; however, it exhibits low activity with ceramides.
