This is also somewhat forcefield dependent (and how you name the histidines
in the PDB as well).

-SH will show up as part of a -SH containing residue (cysteine).
pdb2gmx will attempt to ask you about -S-S- bridges correctly if two
cysteines are close to each other, use the -ss parameter to pdb2gmx. The
manual has a description of how to force a disulfide bridge using
specbond.dat if the starting structure is suboptimal...
