摘要：

Investigations on the structure of horseradish peroxidase (donor: H 2O 2 oxidoreductase, EC 1.11.1.7), including its amino acid and carbohydrate composition, are described. Commercial horseradish peroxidase preparations contain multiple components which can be separated by electrophoresis on starch. The major components have been purified and their properties compared; they do not differ significantly in size, absorption spectrum, enzymatic activity, or amino acid composition. Horseradish peroxidase contains the following sugars: glucose, galactose, mannose, arabinose, xylose, fucose and hexosamine.
