Transmission mechanism The binding ability of five spike population variants, A348T, V367F, G476S, V483A, and S494P with ACE2 has been explored using the protein-protein docking and binding free energy calculations.The A348T, G476S, and V483A variants display reduced affinity t

Protein detail:


Protein name Spike glycoprotein
Uniprot protein ID P0DTC2
Protein length 1273 amino acids
Protein description Spike protein is one of the structural proteins of SARS-CoV-2. The monomeric protein consists of one large ectodomain, a single-pass transmembrane anchor, and a short intracellular tail at C-terminus. It encompasses 22 glycosylation sites. S protein cleaves into two subunits namely S1 and S2 following receptor recognition. Receptor Binding Domain (RBD) in S1 subunit plays a major role in ACE2 receptor binding.

Title Evolutionary and structural analysis elucidates mutations on SARS-CoV2 spike protein with altered human ACE2 binding affinity
Author Sandipan Chakraborty
Evidence Pan-proteomic analysis reveals 113 mutations among them 33 are parsimonious. Evolutionary analysis reveals five RBD variants A348T, V367F, G476S, V483A, and S494P are under strong positive selection bias. Variations at these sites alter the ACE2 binding affinity
