Family

Tryptophan operon leader peptide (IPR012639)

Short name: Trp_leader2

Family relationships

None.

Description

This family consists of the tryptophan operon leader peptides, which are important for the control of tryptophan biosynthesis. The tryptophan operon is regulated by transcription attenuation in response to changes in the level of tryptophan. The transcript of the leader peptide can adopt alternative mutually-exclusive secondary structures that would either result in termination of transcription of the tryptophan structural genes or in transcription of the entire operon [PMID: 12213655].
