In my rush to get the GROMOS96–NAMOT–GROMACS script posted, I forgot that an additional piece of information is required to make this script work smoothly (well, at all). While the nucleic acid residues between the 3' and 5' ends are accounted for by the G-N-G script (DADE, DCYT, DGUA, DTHY), the 3' and 5' ends are not and require having new topology data generated so that all of the atoms on either end are accounted for as NAMOT and NAMOT2 provide them in .pdb format. The .rtp topology additions provided below take care of this.
WHAT'S INCLUDED: Two types of nucleic acids are accounted for with these topologies.
1. FADE, FCYT, FGUA, FTHY – These are the 5' ends of the DNA strands and INCLUDE a hydrogen atom on one of the 5' phosphate oxygen atoms. NAMOT and NAMOT2 output does not include the 5' phosphate by default (dephosphorylates the 5' end before the structure even shows up on the screen). If you want the phosphate group on the 5' end, there's a little bit of file hacking involved. Specifically, you need to add n+1 bases to your structure then delete the first residue (the starting 5' end) up to the sugar oxygen-phosphate junction. This then requires additional topology work that I may or may not get around to automating.
2. TADE, TCYT, TGUA, TTHY – These are the 3' ends of the DNA strands and INCLUDE a hydrogen atom on the 3' C-O oxygen atom. NAMOT and NAMOT2 includes this hydrogen in the output but the label needs to be changed (and atom type assigned).
NOTE: These residue topologies do not work for other GROMOS96 force fields (43a1, 43b1, 43a2, 45a3) or the OPLS-AA/L and Encad force fields available in GROMACS. All of these either do not have the same nucleic acid definitions to begin with or are simply missing required atom type assignments. These may, in fact, be trivial things to fix (the 45a3 being a specific case that is probably 5 steps from a workable script but that I've no need to use and so no need to implement).
HOW TO USE: The additional .rtp content below just gets pasted right into your current ffG53a6.rtp and/or ffG53a5.rtp files. Simply paste it at the bottom. There will be no conflicts with residue specifications if you did not modify these files to begin with. The GROMOS96–NAMOT–GROMACS script takes care of all of the residues between the 5' and 3' end (same naming convention is used as already exists for the d-nucleic acids (DADE, DCYT, DGUA, DTHY)). These residue topologies only correct and assign the 5' and 3' ends.
Simply copy the content below into the bottom of your ffG53a6.rtp and/or ffG53a5.rtp files or download and rename the whole files as provided below. The ";" are comment markers and associated lines are not read by pdb2gmx.
1. Download ffG53a6_NAMOT.rtp and/or ffG53a5_NAMOT.rtp
2. Rename (get rid of _NAMOT)
3. Place into your gromacs/share/top (or gromacs/share/gromacs/top) folder
