Coupling of the NVOC-protected thiothreonyl-tRNA analogues with CPM after DMT group removal. The fluorescence was monitored at ~470 nm following irradiation at 365 nm. Sample 1, CPM treated suppressor tRNA (3 μg/μL); sample 2, CPM treated DMT-thiothreonyl-tRNA (3 μg/μL); sample 3, CPM coupled thiothreonyl-tRNA (3 μg/μL); sample 4, CPM treated DMT-allo-thiothreonyl-tRNA (3 μg/μL); sample 5, CPM coupled allo-thiothreonyl-tRNA (3 μg/μL).
