Usually, cutting a structure in 2 is not enough. You need:
- to find the chemical group where you are going to cut your structure in 2.
- to define connecting groups where you cut your structure.
Thus, this is not cutting a molecule in 2 parts, but more cutting a
molecule in 2 molecules from which some atoms have to be removed.
You can get many information about such an approach .

Finally, after looking at your PDB file, all the hydrogens are located
at the end of the file. You might be interested in using Ante_R.E.D.
which reorders atoms so that hydrogens are always located after the
heavy atom they are bound to.
