Tryp operon
WebApr 13, 2024 · trp operon: The E.coli operon system (a group of genes) that encodes enzymes for the tryptophan biosynthesis is known as trp operon. The entire mechanism of trp operon is regulated by the repressor mediated attenuation process. The E. coli trp operon has 5 different genes. WebExpression of the Escherichia coli tryptophan (trp) operon, in addition to being subject to repression control, is regulated by a second mechanism, attenuation (1). Attenuation involves conditional transcription termination at a site within the trp leader region immediately preceding the structural genes of the operon.
