Metabolic regulation - two-component regulatory systems

7 important questions on Metabolic regulation - two-component regulatory systems

Most signal transduction systems contain two parts, they are called:

Two-component regulatory systems

What is a kinase?

An enzyme that phosphorylates compounds (usualy using phosphate from ATP)

What is sensor kinase and what is its role in TCRS?

It is an enzyme that detects a signal from the environment and phosphorylate itself

Which two compounds do you need in the TCRS?

  1. Sensor kinase protein
  2. regulator protein

What is a phosphatase and what is their role in the TCRS?

It is a component of the feedback loop and removes the phosphate from the response regulator at a constant rate.

The question on the page originate from the summary of the following study material:

  • A unique study and practice tool
  • Never study anything twice again
  • Get the grades you hope for
  • 100% sure, 100% understanding
