Purified neuraminidase preparation from Erysipelothrix rhusiopathiae is studied biochemically. The main physicochemical characteristics of the enzyme are determined: molecular mass, isoelectric point, electrophoretic mobility, chemical nature, UV spectrum, substrate specificity, etc. The obtained data are compared to those for other bacterial neuraminidases.

D004888	Erysipelothrix	A genus of gram-positive, facultatively anaerobic, rod-shaped bacteria that has a tendency to form long filaments. Its organisms are widely distributed in nature and are found in MAMMALS; BIRDS; and FISHES. Erysipelothrix may appear gram-negative because they decolorize easily.	Erysipelothrix rhusiopathiae
D013056	Spectrophotometry, Ultraviolet	Determination of the spectra of ultraviolet absorption by specific molecules in gases or liquids, for example Cl2, SO2, NO2, CS2, ozone, mercury vapor, and various unsaturated compounds. (McGraw-Hill Dictionary of Scientific and Technical Terms, 4th ed)	Ultraviolet Spectrophotometry
D013379	Substrate Specificity	A characteristic feature of enzyme activity in relation to the kind of substrate on which the enzyme or catalytic molecule reacts.	Specificities, Substrate,Specificity, Substrate,Substrate Specificities
