Biochemical characterization of cellulose-binding proteins (CBPA and CBPB) from the rumen cellulolytic bacterium Eubacterium cellulosolvens 5.
The cellulose-binding proteins, CBPA and CBPB, of rumen cellulolytic bacterium Eubacterium cellulosolvens 5 were biochemically characterized, and their properties were compared. Recombinant CBPA and CBPB were a typical 1,4-beta-endoglucanase. Both proteins bound to insoluble polysaccharides such as Avicel cellulose, acid swollen cellulose, lichenan, chitin, and oat spelt xylan. On the other hand, only recombinant CBPB bound to agarose and starch.
