Diversity and modularity of tyrosine-accepting tRNA-like structures

Conservation and phylogenetic distribution of viral tyrosine-accepting tRNA-like structures. (A) Consensus sequence and secondary structure model for the 32 unique TLS^Tyr sequences from 13 distinct viruses in Bromoviridae. (B) Consensus sequence and secondary structure model for the eight unique TLS^Tyr sequences from three distinct viruses in Virgaviridae. The stem–loop labeled as C/D was referred to as the C stem in previous literature; however, it may more closely resemble the optional D stem found in type 1 TLS^Tyr. (C) Phylogenetic distribution of all types of TLSs in the Virgaviridae and Bromoviridae families.
