Novel ganglioside ceramidase isolated from Nocardia and process for producing same

摘要

This invention provides a novel ganglioside ceramidase which has a substrate specificity at least for GD1a, GM1, GM2 and GM3 and acts at least on GD1a, GM1, GM2 and GM3 and catalyzes the reaction of hydrolysis of ganglioside to lysoganglioside and fatty acid.P PThis invention further provides a process for producing the novel ganglioside ceramidase which comprises cultivating ganglioside ceramidase producing strain belonging to the genus Nocardia in a culture medium and collecting ganglioside ceramidase from the culture.
