Biochemical characterization of the reverse activity of rat brain ceramidase. A CoA-independent and fumonisin B1-insensitive ceramide synthase.

Abstract

We have previously purified a membrane-bound ceramidase from rat brain and recently cloned the human homologue. We also observed that the same enzyme is able to catalyze the reverse reaction of ceramide synthesis. To obtain insight into the biochemistry of this enzyme, we characterized in this study this reverse activity. Using sphingosine and palmitic acid… (More)
