Abstract

See full text

This invention provides endo-.alpha.-N-acetylgalactosaminidase (endo-.alpha.-GalNAcase) from a microorganism belonging to the genus Alcarigenes. This endo-.alpha.-GalNAcase is very useful in the analysis of the structure and function of mucin-type sugar chains of glycoproteins, as it is an enzyme that cleaves O-glycosidic linkages of sugar chains of glycoproteins, releasing the sugar chain from said protein.
