Dear All, I have a question regarding the contact interactions between a protein-ligand complex.

Hi Shahid, It certainly would be easier if Chimera allowed you to find contacts/ H-bonds between two arbitrary sets of atoms rather than between one set and "everything else". I will open a feature-request ticket in our Trac database for this with you on the recipient list so you will know when it gets implemented. It will probably be several months before I have time to get to it. In the interim there is an uglier method for getting what you want -- at least for contacts. Basically you delete away all the atoms you don't care about. So to find the aromatic contacts between ligand and non-ligand do this (Favorites->Command Line): del ~aromatic sel :LIG then find contacts between selected atoms and all other atoms. You would have to open a new copy of your system (and close the mutilated one!) to find other interactions. To get charge interactions first add charges to your atoms with the Add Charge tool. You can then select ligand atoms with more than a certain negative charge and non-ligand with more than a certain positive charge (say .1 for this example) with: sel :LIG & @/charge<-0.1 | ~:LIG & @/charge>0.1 then delete all other atoms with: del ~sel then find clashes as above. Then on a new copy of the system find contacts between atoms with the charges reversed.

Hello, Just some additions to what Eric said... (a) you would probably want to use "aromatic ring" instead of "aromatic" -- "aromatic" specifies entire aromatic amino acids, "aromatic ring" specifies aromatic rings in all kinds of molecules. In Eric's example, the ligand residue name was LIG ... so of course, if it has some other name you would use that instead. (b) you could select most (but not all) charged groups based on atom type, for example with the command: select Ng+ | N3+ | N2+ | O2- | O3- That gets atom types in charged groups commonly found in amino acids and nucleotides, except histidines. To include histidines, but only the ones that are charged, you would need to add hydrogens (AddH tool or command addh), add charge (Add Charge tool or command addcharge), and then use select Ng+ | N3+ | N2+ | O2- | O3- | :/amberName=HIP & @nd1,ne2 (The charge assignment process identifies which histidines are doubly protonated and assigns them the AMBER residue name HIP.) A limitation of using this atom type approach is that we do not have thiolate sulfur atom type; if there is specific Cys thiolate you wish to consider, you would have to add that sulfur to the selection manually. There are additional atom types for charged functional groups, but they would not occur in proteins. If manmade ligands are involved, however, you may want to take a look at the list of atom types and possibly add N1+,P3+,S3+,S3- (no, that's not thiolate even though it sounds like it) to the selection command. <http://www.cgl.ucsf.edu/chimera/docs/UsersGuide/idatm.html> Here is an earlier posting about finding salt bridges: <http://www.cgl.ucsf.edu/pipermail/chimera-users/2009-February/003602.html
(c) I wasn't sure if you were also interested in ion-aromatic (cation- pi) interactions. Here some example commands for looking at possible cation-pi interactions. addh addcharge sel aromatic ring | N1+ | N2+ | N3+ | Ng+ | :/amberName=HIP & nd1,ne2 del ~ sel sel aromatic ring findclash sel overlap -1 hbond 0 log true (d) yet another approach is to just get all the contacts of all types and filter them afterwards. However, that would require you to figure out the types of interactions based on the residue and atom names, which might be a lot of work. If using this approach, you might want to remove all the hydrogens first, since they would generally provide a large amount of redundant information. I hope this helps, Elaine On Oct 26, 2009, at 12:06 PM, Eric Pettersen wrote:

Hi Shahid, For (d) there is not really any trick, it is just using the residue and atom names. For example, if you knew C1-C6 in LIG are an aromatic ring, for aromatic-aromatic contacts to PHE you could look for lines in the contacts output with PHE CG,CD1,CD2,CE1,CE2,CZ such as:
LIG 1 C1 PHE 168.A CD2 -0.163 3.488
As I mentioned this would be a lot of work since you would have to know all the atom/res names for a particular type of functional group such as aromatic ring. Also, I don't think this would work for your system because looking at what you sent below, your LIG atoms are not named uniquely (all the carbons are just named C, all the nitrogens named N, etc.).

Hi Shahid, It depends what you want. If those are the results you want (all aromatic-aromatic contacts), it would be the right approach. If not, you would want to use more filtering on the output using names, or deleting some atoms before the calculation as Eric described, to narrow down the results. Elaine ----- Elaine C.
