Structural and simulation analysis of hotspot residues interactions of SARS-CoV 2 with human ACE2 receptor.

ABSTRACT: The novel corona virus disease 2019 (SARS-CoV 2) pandemic outbreak was alarming. The binding of SARS-CoV (CoV) spike protein (S-Protein) Receptor Binding Domain (RBD) to Angiotensin converting enzyme 2 (ACE2) receptor initiates the entry of corona virus into the host cells leading to the infection. However, considering the mutations reported in the SARS-CoV 2 (nCoV), the structural changes and the binding interactions of the S-protein RBD of nCoV were not clear. The present study was designed to elucidate the structural changes, hot spot binding residues and their interactions between the nCoV S-protein RBD and ACE2 receptor through computational approaches. Based on the sequence alignment, a total of 58 residues were found mutated in nCoV S-protein RBD. These mutations led to the structur
