Elongation factor Tu ternary complex binds to small ribosomal subunits in a functionally active state.

Abstract

A complex between elongation factor Tu (EF-Tu), GTP, phenylalanyl-tRNA (Phe-tRNA), oligo(uridylic acid) [oligo(U)], and the 30S ribosomal subunit of Escherichia coli has been formed and isolated. Binding of the EF-Tu complex appears to be at the functionally active 30S site, by all biochemical criteria that were examined. The complex can be isolated with 0… (More)
