Résumé : The ribosome binding region of the messenger RNA for the Esherichia coli car A gene contains two adjacent putative translational start codons, UUG and AUU, both of them unusual. By Edman degradation and mass spectrometry of purified car A protein, we show that only UUG is used in vivo. Translation initiation at UUG in car A appears about half as efficient as at AUG in lacZ.
