Molecular Docking, site directed mutagenesis and molecular dynamic (MD) simulation approaches were used to explore mode of binding and inhibition for human acetylcholinesterase (hAChE) and organophosphates (OPs). More than 200 OPs molecules were investigated using Glide docking module of Schrodinger suite as co-crystal structure between two are not available in protein data bank. In initial screening Trp86 was found to be involved in maximum π-cation interaction on anionic subsite of hAChE other than Ser203 (catalytic site). With extra precision glide docking phoxim ethyl phosphonate (PEP) tops among 200 OPs based on glide docking score while interacted with Trp86, Gly121 and Ser203 whereas MMGBSA score shows less binding affinity than heptenophos and dichlorovos. Trp86 preferred π interaction with ring bearing OPs and hydrophobic interactions with smaller OPs without ring bearing structures. Site directed mutagenesis at Trp86 (Trp86 to Ala86) shown the deterioration of the binding site in terms of size reduction, loss of electrostatic and geometric stabilization in binding cavity and significant reduction in binding of OPs in preferred orientation. Dock score of both wild and mutated hAChE shows a perfect qualitative agreement (R2=64.1%) towards the study. Molecular dynamic simulation (GROMACS 4.5.5) of hAChE-PEP complex for 4×104 pico-second with SPC16 water system at 310K temperature explained the evident role of Trp86 in stabilizing the ligand at P-site of the enzyme. Asp74 and Tyr 124 were noticed in conveying H-bonds. Trp86 have shown consistent and stable distance between residues and ligand. Asp74 and Tyr124 appeared as important residues which contributed H bonds and Ser203 was expected to be closer for interaction to happen as it disappeared during simulation. Study suggests role of Trp86 on binding site is equally important to take consideration. As residue Trp86 plays significant role, it can be taken into consideration for the studies on development of more efficient antidotes to overcome the case of human poisoning.Keywords

Puttaparthi is a birthplace of Bhagawan Sri Sathya Sai Baba and is a small town situated in the district of Anantapur, in Andhra Pradesh. Chitravathi River is the main water-body in Puttaparthi. The river remained dry for many years. Only in the recent years, rainfall events fed water to the river. Last year in 2019 a check-dam was also constructed in Puttaparthi due to which the river water has been stagnant. This review paper aims to assess the surface water quality of the Chitravati River in Puttaparthi after the establishment of the check-dam. In this regard, literature reviews were performed and the paragraphs in the literature reviews were arranged as per three major themes, which are: 1. check-dams, 2. water-quality assessment and monitoring, and 3. non-perennial river systems. By examining these three themes through the literature reviews, key inferences were made. For instance, it can be understood that the check-dam in Puttaparthi is an important water-storage structure, which is likely to have both positive and negative impacts upon the nearby region. Secondly, in order to examine water-bodies like the Chitravati River in Puttaparthi, we have to perform water quality assessment and monitoring. To perform water quality assessment and monitoring for the Chitravati River in Puttaparthi; we have to use important tools like the Water Quality Index (WQI), Water Pollution Index (WPI), and Water Poverty Index (WPI). Thirdly, non-perennial river systems such as intermittent rivers, ephemeral rivers and their key features have been stressed upon by several readings. These are river systems where a river ceases to flow for some months or for several yearas. The Chitravati River in Puttaparthi can be appropriately classified as a non-perennial river system and as an intermittent river. Finally, this review paper concludes through a personal reflection, which stresses upon studying the Chitravati River in Puttaparthi and how the literature reviews will help in this regard.Keywords
