Generally we need a PDB file of the protein, which should employ the format of PDB version 3.0 and be consistent with the AMBER naming scheme for residues (e.g. HID, HIE, HIP for HIS). …

Please consider contributing your AMBER parameters to this database for other AMBER users to download and use, and to provide a starting point for parametrization of similar molecules. A …

Apr 6, 2005 · In this study, two models with a five-coordinated Fe (III) mimicking the sextet spin state of P450s are proposed, which are optimized by semiempirical and ab initio unrestricted …

Nov 22, 2021 · 最近在对含有二价铁离子的蛋白体系进行分子动力学模拟，该问题的关键在于铁离子的力场文件如何创建。 在很多力场中 (如amber forcefield)存在有铁离子的力场参数，但是 …

For the system which has the metal ion inside a residue (like Fe ion inside the HEME residue), user can extract the Fe into a independent residue to perform the modeling. Or bugs may be …

Oct 14, 2011 · We have therefore developed and tested a consistent set of transferable MM parameters based on gas-phase QM calculations of two model systems of the heme—a …
