WebThe proposed model of how tryptophan acts as a corepressor is shown in Figure 1. Which of the following evidence best supports a claim that tryptophan functions as a corepressor? … WebTryptophan functions as a corepressor or an effector molecule that transforms the inactive apo-repressor to an active repressor, which ultimately adheres to the operator sequence …
In prokaryotes, the term corepressor is used to denote the activating ligand of a repressor protein. For example, the E. coli tryptophan repressor (TrpR) is only able to bind to DNA and repress transcription of the trp operon when its corepressor tryptophan is bound to it. TrpR in the absence of tryptophan is known as an aporepressor and is inactive in repressing gene transcription. Trp operon encodes enzymes responsible for the synthesis of tryptophan. Hence TrpR provides a ne… WebSep 13, 2010 · The trp repressor is synthesized as an inactive regulatory protein, but is activated when tryptophan (acting as a corepressor) is available in the culture medium: …
