Frameshift suppressor tRNASufJ is a derivative of tRNAThr. Secondary structure representation of the anticodon stem–loops of tRNAThr and frameshift suppressor tRNASufJ interacting with their respective codons. The C31.5 insertion (red) in ASLSufJ is 5′ to the anticodon nucleotides 34, 35, and 36 causing the codon to increase from three to four nucleotides (blue). The conserved U32·A38 interaction (green) in tRNAThr may be altered in tRNASufJ due to the insertion.
