Homology Modeling and Docking Study of Shewanella Like Protein Phosphatase Involved in Development of Ookinetes in Plasmodium

ABSTRACT Parasites of the genus Plasmodium cause a great deal of morbidity and mortality in worldwide, largely in regions with limited access and indication to the tools necessary to control mosquito populations and to treat human infections of Malaria. Five species of this class of eukaryotic pathogens cause different human disease, with Plasmodium falciparum alone is infecting approximately 500 million people per year and resulting in approximately 1 million deaths. The two genes encoding the Shewanella-like phosphatases of P.falciparum , SHLP-1 and SHLP-2, are conserved among members of Plasmodium family. SHLP is frequently found in asexual blood stages and expressed at all stages of the life cycle of parasite. SHLP deletion results in a reduction in microneme formation, ookinetes (zygote) development and complete ablation of oocyst formation, thereby blocking transmission of parasite.. Structure Modeling of SHLP protein can be helpful in understanding the active site and binding site information and hence can be used for drug designing for therapeutics against malaria. Effective role of Resveratrol is studied against SHLP protein using Docking method to identify protein-ligand interaction scheme and bond formation. Study suggests that resveratrol have strong interaction with SHLP protein and can be used as ligand for drug designing.
