What does the tryptophan bind to when it is present in E. coli?

Biology
2 answers:
7nadin3 [17]3 years ago
5 0

The tryptophan operon found in E coli is a group of genes that encode the enzyme that E coli use for biosynthesis. The operon can be turned on and off. The operon is regulated and controlled by TRP Repressor. When bound to tryptophan, the trp repressor blocks the expression of the operon.

The tryptophan operon is a repressible operon meaning that it is active when there's less TRP available. Therefore, to control the TRP operon when tryptophan is available, the tryptophan molecule must bind to the TRP repressor.

Vadim26 [7]
<h2>Smallpox Vaccine</h2>

Explanation:

  • The smallpox vaccine  is the best way to forestall smallpox.

The effects of anaerobic conditions how would anaerobic conditions (when no o2 is present) affect the rate of electron transport
Romashka-Z-Leto [24]
Anaerobic condition refers to an environmental condition where oxygen is absent. In case of Electron Transport System (ETS) and ATP production, oxygen acts as the final acceptor of electrons. As oxygen is a reactant in ETS and ATP production, unavailability of oxygen can cause no oxidation of the coenzymes or the carriers such as NAPH and FADH2 and no ATP will be produced. Thus, both Electron Transport System and ATP production will stop in the absence of oxygen.
