Abstract

A new reagent, ethyl 4‐azidobenzoylaminoacetimidate, was prepared in a four‐step synthesis starting from 4‐aminobenzoic acid. This compound was used to cross‐link RNA with proteins within the Escherichia coli 30‐S ribosomal subunits. Following the reaction of the imidoester function with protein NH2 groups, photoactivation of the azide binds the other end of the reagent to RNA. The cross‐linked proteins were labelled with 125I and identified by bidimensional gel electrophoresis. Proteins S3, S4, SS, S7, S9, S17, S18 and, in a lower and more variable yield, S12, S13, S14 and S16 were bound to 16‐S RNA. These results were confirmed by isolating cross‐linked protein‐oligonucleotide complexes from 30‐S subunits containing 32P‐labelled RNA.
