Abstract excerpt
The turnip crinkle carmovirus (TCV) coat protein (CP) is folded into R (RNA-binding), S (shell), and P (protruding) domains. The S domain is an eight-stranded beta barrel common to the coat protein subunits of most RNA viruses. A five-amino-acid hinge connects the S and P domains. In assembled particles, each pair of CP subunits is thought to bind a single calcium ion through interactions with three residues of...
