Figure 2

Frequencies of selected glycoside hydrolase (GH) families and carbohydrate binding modules (CBMs) in the (meta-) genome sequences. The data for each entry are rescaled by the total number of GH and CBM domains annotated to the microbial genome or metagenome. The coloring from black to grey indicates domains that are present in high to low amounts, respectively. White indicates absent domain families (“A”, “a”, “B”, “b”, “C”, “c” as described in Table 1).
