| xanthan | enzyme is active on polysaccharides with and without acetate and pyruvate, the optimal size of the substrate appears to be in the range of degree of polymerization (DP) 25-35, i.e. 5-7 repeat units of the polysaccharide, no activity against xanthan modified by reduction of the carbonyl groups or by addition of amine or hydroxylethyl groups | Corynebacterium sp. | oligosaccharides | the combined action of lyase and endoglucanase yields a series of oligosaccharides, each with a side-chain terminating in an unsaturated uronic acid and containing the molar ratio of D-glucose to D-mannose 2:1 | ? | |
