Preparation of misacylated aminoacyl-tRNA(Phe)'s useful as probes of the ribosomal acceptor site.

Abstract

Several pyroglutamylaminoacyl-tRNA's were prepared by T4 RNA ligase mediated condensation of synthetic pyroglutamylaminoacyl-pCpA's with tRNA's from which the last two nucleotides at the 3'-end had been removed. The derived pyroglutamylaminoacyl-tRNA's were incubated in the presence of calf liver pyroglutamate aminopeptidase, which effected their conversion… (More)
