An immunological assessment of lysosomal enzymes and other macromolecules sulfated during vegetative growth of Dictyostelium discoideum

Western blotting and immunoprecipitation data indicated that lysosomal enzymes represent a subset of the sulfated macromolecules present in vegetative Dictyostelium discoideum amoebae and account for less than 2.5% of the total sulfate incorporated during vegetative growth. These data suggest that the majority of the highly sulfated macromolecules of vegetative D. discoideum amoebae are not related to the lysosomal enzymes.
