Isomeric aminoacyl-tRNAs are both bound by elongation factor Tu.

Hecht, S M, Tan, K H, Chinault, A C, Arcari, P

Recent suggestions that elongation factor Tu (EF-Tu) is specific for 2'-O-aminoacyl-tRNA, as compared with the 3'-isomer, prompted us to assay [3H]aminoacyl-tRNAs from Escherichia coli terminating in...
