Figure 6.
Phylogenetic analysis of Arabidopsis ubiquitin (Ub) E2s with sequences from several other species related to yeast Ubc6 and Ubc7. Other E2s used are from rice (Oryza sativa—Os), yeast (Saccharomyces cerevisiae—Sc), fruit fly (Drosophila melanogaster—Dm), and human (Homo sapiens—Hs). The clades of E2s related to yeast Ubc6 and Ubc7 (and the Arabidopsis E2 subfamilies) are indicated.
