Amino acid accepting structures in tymovirus RNAs.
We have shown that the 3' terminal nucleotide of tymovirus RNA binds valine as do tRNAs. We have mainly studied eggplant mosaic virus which presents two types of particles. The heavy particle contains the genome which binds valine and a 4S satellite RNA esterified by lysine. The light particle contains 4S RNAs, possessing various acceptor capacities. Among these 4S RNAs we have identified the host plant tRNAsVal, a single tRNA Lys and probably the moiety of the genome which accepts valine.
