Immunological evidence to show that the N-acetylglucosaminidase and N-acetylgalactosaminidase activities of Dictyostelium discoideum reside in the same protein molecule.
Ontology highlight
ABSTRACT: Antibodies were produced against purified beta-N-acetylhexosaminidase from Dictyostelium discoideum. Ouchterlony tests produced a single precipitin band with both beta-N-acetylglucosaminidase and beta-N-acetylgalactosaminidase activities. Both activities were co-precipitated in exactly the same proportions in quantitative immunoprecipitation reactions. We conclude that one enzyme protein catalyses the hydrolysis of both N-acetylglucosaminides and N-acetylgalactosaminides.
