Interaction of the trp repressor and RNA polymerase with the trp operon

Journal of Molecular Biology, 1975
Abstract An in vitro transcription system for the tryptophan operon of Escherichia coli was used to determine the mechanism by which trp † repressor inhibits transcription of the operon. It was found that trp repressor-binding prevents binding of RNA polymerase to the operon. It was also observed that when polymerase is prebound to the trp promoter,

The regulatory region of the trp operon of Serratia marcescens

Nature, 1978
The nucleotide sequence of the regulatory region of the trp operon of Serratia marcescens is presented. It contains a transcription termination control site in the transcribed leader region preceding the first structural gene of the operon as well as a regulated promoter/operator transcription initiation region.

Sequence analysis of the Brevibacterium lactofermentum trp operon

Molecular and General Genetics MGG, 1987
Brevibacterium lactofermentum, a Gram-positive bacterium, is a commercially important amino acid producer. In this organism, the tryptophan biosynthetic enzymes are encoded within a 7725 bp HapII-BamHI fragment. Seven open reading frames were identified as trp genes by complementation tests with various B. lactofermentum and Escherichia coli tryptophan
