主　　题：Respiratory syncytial virus Stability Intra-protein interactions Tunnels Drug discovery 

摘      要：The current scenario of COVID-19 makes us to think about the devastating diseases that kill so many people every year.Analysis of viral proteins contributes many things that are utterly useful in the evolution of therapeutic drugs and vaccines.In this study,sequence and structure of fusion glycoproteins and major surface glycoproteins of respiratory syncytial virus(RSV)were analysed to reveal the stability and transmission rate.RSV A has the highest abundance of aromatic residues.The Kyte–Doolittle scale indicates the hydrophilic nature of RSV A protein which leads to the higher transmission rate of this virus.Intra-protein interactions such as carbonyl interactions,cation-pi,and salt bridges were shown to be greater in RSV A compared to RSV B,which might lead to improved stability.This study discovered the presence of a network aromatic–sulphur interaction in viral proteins.Analysis of ligand binding pocket of RSV proteins indicated that drugs are performing better on RSV B than RSV A.It was also shown that increasing the number of tunnels in RSV A proteins boosts catalytic activity.This study will be helpful in drug discovery and vaccine development.
