Technical information
General information
Name: Ffa2_apo-empty (apoform)
PDB id: 8J23
Activation state: Active
Description: Simulation aims to observe structural features of FFA2 in the absence of G-protein and any ligands. It will be used for comparison to docking-based simulations. It produced NPT ensemble from 3 replicas of 1000 ns Langevin dynamics (T=310.15K, gamma=1ps-1) with semi-isotropic Berendsen barostat (P=1bar, tau=1ps) and 9A noncovalent cutoff.
