  1. Potential substrates, likely enzyme activities, EC number and the number of family members are shown. The accession numbers of proteins in each GH category are tabulated in Additional file 2. Assessments of likely substrates and enzyme activities were based on information provided in the cited references. HG = homogalacturonan; AGP = arabinogalactan protein; RGI = rhamnogalacturonan I.
