Potential substrates, likely enzyme activity, EC number and the number of family members are shown. References used to determine the potential activities of each family are shown. CBMs do not have catalytic activity. The details of each protein in each family are found in Additional file 2. PGA = polygalacturonic acid; GlcNAc = N-acetylglucosamine; na = not available.
