Abstract:

Squalene epoxidase (SE) is one of the important enzymes of the triterpenoid saponin biosynthesis pathway in plants. In this study, SE protein sequences from 16 species of plant were analyzed using bioinformatics methods. The secondary structure, three dimensional structures for these enzymes were predicted. The physico-chemical properties including pI, molecular weight (MW), GRAVY, subcellular localization and conserved domains were also studied. The results of sequence comparison showed that there is high identity between SE proteins from different plants. Phylogenetic analysis showed that SE proteins from plants, mammals, fungus can be clustered into different branches, the relationship was closer within plant species. These results indicated that SE proteins from various species have conserved region, and were derived from a common ancestor.
