Simplified schematic overview of all the proteins expressed by Paenibacillus O199, their role in the hydrolysis of cellulose and hemicellulose (xylan, glucomannan, xyloglucan and mixed-linkage glucans), and their location. Only proteins characterized as cellulases and hemicellulases are shown. Proteins marked with an asterisk were only expressed on cellulose, and proteins marked with a double asterisk were only expressed on wheat straw. Question marks indicate unclear location. Polysaccharides structures are based on Burton et al.
