Hello,
I want to simulate heme of hemoglobin.I am using Gromacs version 5.0.7. and force feild GROMOS 96 43a1 and spc water model.I built Heme topology on Prodrg and Swiss param but Prodrg doesnt accept heme while Swiss param give errors. Kindly tell me appropriate force feild which I should use and How to generate iron and oxygen topology? or any alternative which I should use.Heme topology is available in almost all force feilds but It is for FE2+ not for FE3+ and I want to simulate FE3+. If it is possible, kindly please generate topology for heme containing oxygen. I shall be really very thankful to you.
This is the ligand , the heme atom.
