The 24 translation assays. (A) l-amino acids and N-alkyl-l-amino acids synthesized in NVOC-amino-protected form on the dinucleotide pdCpA for ligation onto tRNAminusCA transcripts (see Supporting Information). A, Ala; F, Phe; P, Pro; hP, 4-hydroxy-Pro; NMA, N-methyl-Ala; NMF, N-methyl-Phe; NBA, N-butyl-Ala; NBF, N-butyl-Phe. (B) Coding sequences of mRNAs: f, formyl; X, amino/N-alkyl amino acid from (A).
