This peptide contains two adjacent tryptophan residues, which is unusual, since tryptophan is a fairly uncommon amino acid (about one in a hundred residues in a typical E. coli protein is …

The Tryptophan operon leader is an RNA element found at the 5′ of some bacterial tryptophan operons. The leader sequence can form two different structures known as the terminator and …

An essential feature of this attenuation mechanism is the synchronization of translation of a 14-residue leader peptide coding region, trpL, with transcription of the operon's leader region. …

2022年9月3日 · The tryptophan operon is the regulation of transcription of the gene responsible for biosynthesis of tryptophan. The tryptophan (trp) operon contains five structural genes …

2024年11月2日 · The tryptophan operon consists of promoter, operator which overlaps with the promoter followed by the leader sequence of about 162 nucleotides and five structural genes …

2008年4月1日 · Survival and replication of most bacteria require the ability to synthesize the amino acid l -tryptophan whenever it is not available from the environment. In this article we …

2016年1月1日 · The site of attenuation (a) is within the trpL (tryptophan leader) sequences. Before attenuation becomes effective, the RNA polymerase pauses at the tp site in the trpL …

2016年11月11日 · In E. coli, the tryptophan operon is a DNA segment containing a promoter (trpR) where transcription starts and regulation by repression takes place, a leader region …

This protein is involved in control of the biosynthesis of tryptophan. Showing features for peptide. Search… Submit a new modelling project… Search… Any medical or genetic information …

2019年6月23日 · Although this operon is a classic example of how transcription is attenuated in the synthesis of the TrpL leader peptide, GenBank has only 215 trpL genes, of which 151 have …
