[TR] Physicists Discover Quantum Law Of Protein Folding

It's easy to think that proteins ought to fold more quickly as they cool down and then unfold more quickly as they heat up. But the actual relationship is both nonlinear and asymmetric, meaning that unfolding is not the reverse of folding.

Molecular biologists have put forward various mechanisms to explain this, such as the nonlinear interaction between water and hydrophobic parts of proteins. But none of these are very convincing.

That looks set to change with the work of Liaofu Luo at the Inner Mongolia University and Jun Lu at the Inner Mongolia University of Technology, both in China. They say that the way folding depends on temperature all becomes clear as soon as you take quantum mechanics into account.

Once again,

The Chinese have succeeded applaud.gif

Reading articles like these makes me wish that I had decided to study physics / mathematics instead of psychology...

How unfortunate that Einstein dismissed quantum theory. Science's most exciting field strikes again.

the only reason why he did that was because he didn't like the idea of him not being able to explain the idea of electrons being in more than one place.

Oh damnit... I decided against taking Quantum physics this year... Maybe I'll take it up next semester in order to become one of these so called quantum biologists biggrin.gif

This sounds so cooool biggrin.gif

That's what I said. What's with the question without a question mark and a lol at the end?

Don't have time to read the full article.
What are the implications, if any, of this on research into protein folding (i.e. F@H and the likes)?

Algorithms that are more accurate and maybe more efficient. If you don't have to model the steps between points A and B, and can represent amino acids as probability clouds rather than discrete molecules, it might require less computing time to simulate the folding process.
