pdb files generated by VMD don't contain bonding information.
when you load the file, the bonds are recomputed from the
element information inferred from the atom names.
the result may not be consistent with what you expect.
if you first load a .psf file with the correct topology information
and then load the .pdb file, then it should look the same as
before, since the bonding information is taken from the .psf.
