    Abstract

    The role of the scaffolding proteins, cellulose binding protein B and C (CbpB and CbpC, respectively) were identified in cellulolytic complex (cellulosome) of Clostridium cellulovorans for efficient degradation of cellulose. Recombinant CbpB and CbpC directly anchored to the cell surface of C. cellulovorans. In addition, CbpB and CbpC showed increased hydrolytic activity on crystalline cellulose incubated with exoglucanase S (ExgS) and endoglucanase Z (EngZ) compared with the activity of free enzymes. Moreover, the results showed synergistic effects of crystalline cellulose hydrolytic activity (1.8- to 2.2-fold) when CbpB and CbpC complex with ExgS and EngZ are incubated with cellulolytic complex containing mini-CbpA. The results suggest C. cellulovorans critically uses CbpB and CbpC, which can directly anchor cells for the hydrolysis of cellulosic material with the major cellulosome complex.
