Action of Fraction F504.2 on the glycopeptides of bovine IgG, ovalbumin, fetuin, and porcine thyroglobulin (units A and B) was not able to cleave the core di-N-acetylchitobiose linkages of these glycopeptides; so this enzyme has not the same specificity as the endo-β-N-acetylglucosamini-dases purified from the culture fluids of Diplococcus pneumoniae (4), Streptomyces (5), and Clostridium perfringens (6).
