Molecule phylogenetic analysis of gene encoding aspartate aminotransferase

Aspartate aminotransferases is an effective catalyst in the amino-transformation rection, and plays an important role in the metabolism of carbon and nitrogen in cells. In this study, the conserved genes encoding Aspartate aminotransferase in different species were analyzed by bioinformatics, and found gene (AAF19543) from Arabidopsis thaliana shows obvious comparability with those from some species in Dicotyledon and Monocotyledon. Furthermore, The phylogenetic tree showed that these species analyzed were divided into two branch, one branch was composed of Protist, Eukaryotes, the other consist of Pan troglodytes and Tribolium castaneum, and the Eukaryotes was further divided into two branch, which is mostly consistent with biology system.
