proteins

Post by kandarp shah » Mon Jan 16, 2006 5:06 am

hey, i am totally lost on this question please help.

1)Name a protein specified by a gene that has been highly conserved in organisms ranging from bacteria to humans. Speculate as to why it has been conserved.
-My GUESS- INSULIN

please reply i do not know the anwer this was just my uneducated guess.
thanks....thanks.

I don't think so. Insulin in bacteria is artificial, it is created by genetic engineering :)

I read somewhere, it is a protein that initiates PCD or apoptosis. Every cell needs this mechanism, to commit suicide, to prevent infections spreading over. I have to search for the name :?

Wait a minute, it must be kind of membrane protein, because every cell has a membrane and needs a protein structure to bridge between external and internal environment. Say receptor, carrier, canal protein... hmm :?

I'll say one thing...it's aquaphorin. It's a protein acts as a water permeases in every cells (specially in microorganisms).
PS: you've to differ between higher cells and microorganisms boss...
Q: Why are chemists great for solving problems?
A: They have all the solutions.

hey,
i think you both guys are right it has to be a membrane protein because every cell has membrane and they need proteins like AQUAPORINS to maintain cell's internal water content.

are there any other proteins that cell membrane need other than Aquaporins?

thanks.

hello, people.. am i the only one seeing the obvious? Genes that code for enzymes in glycolysis!
