Abstract: A glycopeptidase was isolated from sweet almong and purified by a modified approach including hydrophobic chromatography on Butyl-TSK 050 S as the final step. The homogeneous protein (molecular mass 71 kD) was obtained by gel-filtration on Sephacryl S-200, its specific activity being 203 units/mg. The sequence of ten N-terminal amino. acid residues of the enzyme's protein moiety was determined.
