Glutamate dehydrogenases. Schematic representation for presence/absence of glutamate dehydrogenases. A: Left column: assimilative GDH1 and GDH3 from Saccharomyces cerevisiae and putative GDH from Arabdopsis thaliana; Central column: catabolic GDH2 from Saccharomyces cerevisiae; Right column: catabolic GDH1, GDH2 and GDH3 from Arabdopsis thaliana. Taxonomic tree displayed at phyla level. Circles represent detection of complete proteins and triangles detection of complete and fragmented proteins. Colors are as for Figure 1. Saccharomyces cerevisiae (Ascomycota) and Arabidopsis thaliana (Streptophyta) were used as seeds. B: Phylogenetic tree with eukaryotic sequences from glutamate dehydrogenase isoforms. Green branches: EC22.214.171.124; Red branches: EC:126.96.36.199; Blue branches: EC:188.8.131.52.
