Hi Justin and Roland, we are interested in simulating a glycosilated protein. We already have a pdb file (and psf topology) with the charmm/namd format/nomenclature. We managed to have pdb2gmx read the carbohydrate residues by adding the relative entries in the residuetypes.dat, however we have not yet been able to add the covalent bonds necessary to reproduce the correct branched carbohydrate chains. Is there any solution for that? Roland seems to have one, although suboptimal. would it be possible to share it?

Using specbond.dat might help, but often these types of patches will require modification of atom types depending on the linkage, so there isn't any solution completely within pdb2gmx that will suffice, outside of building a residue from the original PRES entries in the CHARMM files, which is what it sounds like Roland's program does. -Justin -- == Justin A.

Re: [gmx-users] CHARMM36 force field available for GROMACS
Hi All, To follow up on a few recent issues that we have discovered and/or have been reported here, we have updated our CHARMM36 force field files. As always, they can be downloaded from: http://mackerell.umaryland.edu/CHARMM_ff_params.html Here is a list of changes: 1. An error in ions.itp was propagated from the old CHARMM27 files, which assigned a -2 charge to Zn. The .rtp entry for Zn was correct, so if you are studying any metal-containing proteins, the simulations should be fine if the topology was generated with pdb2gmx. It would only matter if you used genion to add Zn to the system, so the error would be fairly obvious in the accumulation of negative charge. 2. An atom name in the LSN (neutral lysine) .rtp entry was incorrect. This is also a rather obvious error, as pdb2gmx would die with a fatal error when trying to generate impropers. 3. Per recent posts to the list, we have corrected errors related to H5' nomenclature in RNA. Bonds would have been missing between C5' and H5'1/H5'2, causing H atoms to go flying around, or the simulation may have just simply crashed. DNA simulations done with this force field are not affected by this problem. Support for RNA has further been enhanced by the addition of .hdb entries for ADE, CYT, GUA, and URA. 4. We have added angle parameters for NH2-CT1-CT1 to fix a problem with missing angle parameters for neutral N-terminal amino acids like Ile and Thr. 5. We added heme and cholesterol (CHL1), per user requests. If anyone has comments, questions, etc. about these force field files, please feel free to post them here or send them to me. Happy simulating! -Justin -- == Justin A. Lemkul, Ph.D. Ruth L.

Thanks for the clarification. *Bonds involving H5' and H5'' in RNA residues should indeed be changed to the H5'1 and H5'2 nomenclature.* Even though H5' and H5'' are connected to the same atom, what would be the problem to keep these H atom names H5' and H5'' instead of changing them to H5'1 and H5'2?

Re: [gmx-users] CHARMM36 force field available for GROMACS
Thanks, but I'll have to ask you something again. :) On Sun, Mar 9, 2014 at 5:00 PM, Justin Lemkul jalem...@vt.edu wrote: On 3/9/14, 7:23 PM, Jim wrote: Thanks for the clarification. *Bonds involving H5' and H5'' in RNA residues should indeed be changed to the H5'1 and H5'2 nomenclature.* Even though H5' and H5'' are connected to the same atom, what would be the problem to keep these H atom names H5' and H5'' instead of changing them to H5'1 and H5'2? In principle, no, the CHARMM-specific names should work fine, but only if you add corresponding entries in the merged.arn file to translate between CHARMM and Gromacs nomenclature. We made the naming change to interface smoothly with the Gromacs hydrogen-generation (.hdb) mechanism. If you have a coordinate file that complies with CHARMM naming, i.e. from CHARMM-GUI, then simple sed statements take care of any issues. Although this makes sense, it also brings other questions. I don't really understand the significance of the *hdb file - isn't its sole purpose to add hydrogens to coordinates that don't have all hydrogens? Second, what kind of a file is merged.am? I've never seen such a file... Third, if the H2' and H2'' of the RNA nucleotides do not correspond to the Gromacs nomenclature as well, then where exactly is their CHARMM-Gromacs conversion taken care of? In other words, if I use H5' and H5'' names instead of H5'1 and H5'2, isn't this equivalent to using the H2' and H2'' names instead of H2'1 and H2'2 in terms of translating between nomenclatures? Basically, I have a CHARMM 36 solvated file with all necessary hydrogens generated with CHARMM, do some rotation (for PBC matching) and then something like this: cat $pdbfile | sed 's/TIP3/SOL /' | sed 's/ OH2 SOL/ OW SOL/' | sed 's/ H1 SOL/ HW1 SOL/' | sed 's/ H2 SOL/ HW2 SOL/' | sed 's/ SOD SOD/ NA NA /g ' | sed 's/ CLA CLA/ CL CL /g' I don't change the names of any other atom or residue. I use H5' and H5''. I change ADE, GUA, CYT, URA to use the H5' and H5'' atom names in the merge.rtp as well. I don't touch the [bonds] because they already use these atom names. I generate a topology and *.gro with pdb2gmx.
