The Apicomplexan parasite Plasmodium vivax is responsible for causing greater than 50% of human malaria cases in Central and South America, Southeastern Asia and the Indian subcontinent. The rising severity of the disease and the resistance shown by the parasite towards usual therapeutic regimen has put forth a demand for a novel drug target to combat this disease. Apicoplast, an organelle of prokaryotic origin, and its circular genome are being looked upon as a potential drug target. The Apicoplast genome is known to carry various genes of functional importance, including the gene encoding for the protein Elongation factor Tu (tuf A) that participates in the translational process in prokaryotes. The tuf A gene is translationally active within the organelle and is believed to be one of the best functionally conserved protein throughout the species. Till date there are no reports of this gene from another major human malaria parasite P. vivax. This is the first report detailing any complete gene analysis from the Apicoplast genome of the Indian P. vivax isolates. The study predicts and evaluates the complete Apicoplast Elongation factor tuf A gene and EF–Tu protein at primary, secondary and tertiary structure level. In addition, a comparative phylogenetic analysis using this gene is done to understand the evolutionary status of Indian P. vivax isolates. Our study shows that although the Indian P. vivax EF–Tu is not showing any major difference at the structural and predicted functional level, it is diverging way ahead from the P. vivax clade. |
