Receptor/ligand binding

Post by rendev01 » Wed Apr 21, 2010 2:56 am

Hi

I would like to know is there any software or model out there that could simulate or predict the receptor-ligand binding events? Assuming I've functionalized a surface with a million receptor molecules and I exposed the surface to a few thousands target molecules. How would the target molecules binds to the receptor? Would each of the target molecule randomly pick a receptor and bind to it or would they follow a certain pattern?

Thanks in advance.

Cheers

Of course, they would bind in accordance to some affinity and of course, if they didn't fit the binding site, they couldn't bind at all ;)

One member here did post several databases, so try to look for it. I think in Bioinformatics. Otherwise you had to use physical chemistry, modeling and entropy calculations

Cis or trans? That's what matters.

Thanks for the reply. I appreciate it a lot.

The affinity gives me the knowledge of the binding strength of the molecule but I'm wondering whether the target molecules will bind with a uniformly distributed coverage on the surface?

if you had the same receptors and the same concentration all around, than yes

if it's just a diffusion process, it's hard to see why they would have any pattern.

Honestly I don't understand what are talking about exactly..
Could you be more specific regarding the topic?
