[gmx-users] How to make a CG topology for a modified residue?

[Du Jiangfeng (BIOCH)]

Dear Everyone,

I am going to simulate the interaction of prothrombin's Gla domain with membrane in martini force field. Here I encountered a problem: there are 10 modified GLUs in GLA domain. Martini force field can't recognize them. How should I overcome this problem?

What I want to do now is to add this modified residue into martini force field, but I do not know whether it is feasible or logical? What's worse, I really don't know what is BNLN, BNKB or ANGL? Where can I get some references about this story?

Any help will be appreciated,
