RESUMO
Here we report the identification of the Escherichia coli trp leader peptide synthesized in vivo. We identified the peptide in UV-irradiated maxicells by selective labeling with radioactive amino acids which are included in the predicted sequence of this peptide. Our results support the hypothesis that translation of the peptide-coding region of the leader RNA has a role in the mechanism of attenuation of biosynthetic operons in general and in the E. coli trp operon in particular.
