Add Missing Hydrogens

Add missing hydrogen atoms?

Add hydrogens appropriate for pH

Add Water/Membrane

Add a water box or membrane surrounding the model?

Add water box

%s
Custom box dimensions (in nm):
Geometry with padding (in nm): ?

Add membrane and water

The membrane will lie in the XY plane and be centered at Z=0. Make sure the protein is properly oriented and positioned. When possible, it is easiest to use a PDB file from OPM since they are already properly positioned.

Lipid type:

Minimum padding around protein: (nm)

Ions will be added to neutralize the model. You can optionally add more ions based on a desired bulk ionic strength.

Ionic strength (molar):
Positive ion:
Negative ion:
