Fig. 5From: Classification, substrate specificity and structural features of D-2-hydroxyacid dehydrogenases: 2HADH knowledgebaseAbundance of the nine biochemically studied 2HADH subfamilies in selected model organisms. The size of each square corresponds to the number of proteins belonging to a given subfamily encoded in the given organism. The tree topology was obtained from iTOL [112], and proteomes were downloaded from KEGG [113] (Additional file 9: Data file S2)Back to article page
