[gmx-users] 11-cis retinal topology problem

2013-07-06 Thread Albert
Hello guys: I am building 11-cis-retinal topology these days. Here is what I did: first of all, I build a small peptide like compound which contains:11-cis-retinal connected to the protonated sidechain of LYS, ACE and NME capped the N-term and C-term of the LYS respectively. With this

Hi Friends, I am working on peptide self assembly. I simulated two peptide which are random coil and apart from each other. As the time process they start to interact and form antiparallel beta sheet structure. My plan is to find the energy difference in random coil to beta shhet
