The importance of the specific action of glycosidases for maintaining normal cell function has been reflected in the heritable diseases characterized by their absence. Our appreciation of the role of glycosidases in the biological system would be enhanced by a better understanding of their substrate specificity. In this communication, we wish to use the specificities of ß-galactosidases isolated from Escherichia coli, jack bean and human liver to point out that the conventional nomenclature for glycosidases based solely on their specificity toward the glycon moiety of the substrates is misleading and sometimes confusing. In addition, the specificity of endo-ß-galactosidase isolated from Escherichia freundii will be presented.
