Spontaneous mutations restore the viability of tick-borne encephalitis virus mutants with large deletions in protein C.

Abstract excerpt

The capsid protein, C, of tick-borne encephalitis virus has recently been found to tolerate deletions up to a length of 16 amino acid residues that partially removed the central hydrophobic domain, a sequence element conserved among flaviviruses which may be crucial for virion assembly. In this study, mutants with deletion lengths of 19, 21, 27, or 30 residues, removing more or all of this hydrophobic domain,...
