Saposin D is a sphingolipid activator protein required for the lysosomal breakdown of ceramide to a fatty acid and sphingosine by acid ceramidase. The crystal structure of saposin D has been determined in two different crystal forms, resulting in a total of six crystallographically independent views of this small 80-amino-acid protein ...
