Application
Chondroitinase B from Flavobacterium heparinum has been used in a study to assess the structural characterization and antithrombin activity of dermatan sulfate. Chondroitinase B from Flavobacterium heparinum has also been used in a study to investigate the chondroitin lyase action pattern via liquid chromatography–mass spectrometry.
The enzyme from Sigma has been used for the analysis of the frequency of iduronic acid in dermatan sulfate dodecasaccharide. It has also been used to digest dermatan sufate (DS) in melanoma cells. This digestion resulted in decreased proliferation and invasiveness of tumor cells, thereby suggesting a role for DS in metastasis.
Biochem/physiol Actions
Chondroitinase B degrades only chondroitin sulphate B producing oligo- and tetra-saccharides, and an unsaturated 4-sulphated disaccharide. It has an optimum temperature of 20 °C and an optimum pH of 8.0. The enzyme activity is inhibited by 50% using 0.1 M NaCI. Co2+, Fe3+ and Ba2+ also inhibit its activity.
Other Notes
One unit will form 0.1 μmole of unsaturated uronic acid per hr at pH 7.5 at 25°C using chondroitin sulfate B as substrate.

Liquid chromatography-mass spectrometry was applied to determine the action pattern of different chondroitin lyases. Two commercial enzymes, chondroitinase ABC (Proteus vulgaris) and chondroitinase ACII (Arthrobacter aurescens), having action patterns previously determined by viscosimetry and gel electrophoresis were first examined.

A chondroitinase that degrades only chondroitin sulphate B was isolated from Flavobacterium heparinum, and separated from a constitutive chondroitinase AC also present in extracts of F. heparinum. The enzyme acts only on chondroitin sulphate B, producing oligo- and tetra-saccharides, plus

Injury to the CNS of vertebrates leads to the formation of a glial scar and production of inhibitory molecules, including chondroitin sulphate proteoglycans. Various studies suggest that the sugar component of the proteoglycan is responsible for the inhibitory role of
