We have analysed the regulatory behaviour of deletion mutants lacking different segments of the leader region of the tryptophan operon of Serratia marcescens. Our results support the model in which a particular RNA structure, the terminator, is recognized during transcription as a transcription termination signal, and an alternative RNA structure, the anti-terminator, prevents formation of the terminator. It appears that the role of translation, ribosome stalling and shifts between alternative RNA secondary structures, is simply to regulate formation of the terminator.
