Discussion 2 : Protein Function And Gases

DQ 2 Topic: Protein Function And Gases

Topic: Protein function and gases

Part 1:  

This week you learned about the importance of three-dimensional  structure (conformation) and protein function and about the role of  enzymes for many cellular process, ranging from metabolism to  regulation.
This week you further learned that the 3D structure of  proteins and enzymes can be modified and altered by many chemicals,  both, endogenous or through external exposure.

This week I want you to do some research (using  NCBI PubMed) and look for recent scientific articles showing the impact of gases (e.g. nitric oxide, superoxide anion radicals, carbon monoxide or hydrogen sulfide) on proteins or enzymes critical for normal cell functioning. 

Select ONE article of your interest and start a discussion  with your class mates. Make that you name your selected article in a  reference section of your initial posting.

As you work on this assignment address and discuss with your class mates the following:

1. Which gaseous chemical has been studied?
2. Which effect(s) of your selected gaseous chemical where reported in your selected scientific publication?
3. What is/are the known biological target(s), i.e., enzymes, proteins, of the gas?
4. What is/are the known effect(s) of the gas on the target enzyme or protein?
5. Which enzymes is/are known to produce this gas?
