Table 1.
A summary of side chain and main chain hydrogen bonding analysis between the polybasic FCS and other part of the S protein of SARS-CoV-2. In this table, the residue naming scheme is Chain ID_residue name_residue number, ∠ADH represents the angle formed by acceptor (A), donor (D) and hydrogen (H) (∠ADH).
