We report here the expression of a bacterial sphingomyelinase in mammalian cells as a functionally active form. A chimeric Pseudomonas sphingomyelinase fused with the lysosomal sorting motif of lysosomal acid phosphatase was sorted to lysosomes in mammalian cells. As expected, the chimeric SMase hydrolyzed sphingomyelin in vivo to produce ceramide, part of which was converted to glucosylceramide.
