Endo-N-acetyl-beta-D-glucosaminidase H (Endo H) was purified to homogeneity (3000-fold) from a culture filtrate to Streptomyces plicatus. The key step was substrate-affinity chromatography, which afforded a 1000-fold purification and yielded a protease- and exoglycosidase-free preparation of Endo H. Proteins from the crude sample were applied to the substrate-affinity column, consisting of yeast-invertase glycopeptides bound to Sepharose-immobilized concanavalin A. After washing off the unbound proteins, Endo H was quantitatively eluted by methyl alpha-D-mannopyranoside. Various conditions were tested to achieve an optimal binding of Endo H to this substrate-affinity gel. After substrate-affinity chromatography, Endo H was separated from the coeluted gylcopeptide substrate and some protein impurities by gel filtration and hydrophobic chromatography.
