The present invention relates to a novel endoglycoceramidase whose hydrolytic activity has been substantially reduced or eliminated, such that the enzyme is useful for synthesis of glycolipids from a monosaccharide or oligosaccharide and a ceramide. More specifically, the endoglycoceramidase is a mutant version of a naturally occurring endoglycoceramidase, preferably comprising a mutation within the active site or the nucleophilic site of the enzyme and more preferably comprising a substitution mutation of the Glu residue within the active site or the nucleophilic site. Also disclosed are a method for generating the mutant endoglycoceramidase and a method for enzymatically synthesizing glycolipids using this mutant enzyme.
