Sphingolipid ceramide N-deacylase (SCDase) catalyzes reversible reactions in which the amide linkage in glycosphingolipids is hydrolyzed or synthesized. While SCDases show great value for the enzymatic synthesis of glycosphingolipids, they are relatively poorly characterized enzymes. In this work, the enzymatic
