The oligosaccharide chains of microheterogeneous bovine pancreatic DNAases were characterized by the lectin-nitrocellulose sheet method. The active fractions of the DNAases from column chromatography showed four major and several minor spots on a two-dimensional polyacrylamide gel. They were transferred on to nitrocellulose sheets and treated with glycosidases (neuraminidase, endo-beta-N-acetyl glucosaminidase H or F, or peptide N-glycosidase F) and treated with peroxidase-coupled lectins (concanavalin A, Ricinus communis agglutinin or wheat-germ agglutinin). From the results, the most probable oligosaccharide types were proposed to be as follows: the four major spots contained components which had high-mannose type or hybrid-type oligosaccharides, such as those susceptible to endo-beta-N-acetylglucosaminidase H. In addition, spot 1 contained a complex-type biantennary oligosaccharide without sialic acid and spot 3 contained a tri- or tetra-antennary complex-type oligosaccharide with sialic acid. The component corresponding to spot 2 had a hybrid-type oligosaccharide chain with a 'bisecting' acetylglucosamine, linked 1-4 to the beta-mannose residue of the trimannosyl core, and the component corresponding to spot 4 had a high-mannose-type oligosaccharide chain.
