Phylogenetic relationships of several yeast aminotransferases. The phylogeny was derived from a maximum likelihood analysis of various orthologues of the ScAro8 and ScAro9 proteins and was rooted with Ralstonia solanacearum Q8Y2V3. Bootstrap values based on 100 replicates are indicated at the nodes. Kl, Kluyveromyces lactis; ASGO, Ashbya gossypii; CAGL, Candida glabrata; SACE, Saccharomyces cerevisiae; YALI, Yarrowia lipolytica; DEHA, Debaryomyces hansenii; CAAL, Candida albicans.
