The presence of a mobile element in the coat protein of pepper ringspot tobravirus (PRV) has been established by 1H n.m.r. spectroscopy; two-dimensional correlation spectroscopy (COSY) measurements show that this element consists of alanine, asparagine, glycine, proline, serine and threonine only. By reference to the amino acid sequence of the coat protein, it is concluded that the mobile element is associated with the C-terminal region and consists of between 11 and 38 residues.
