Where did you get your PDB file? The PDB file specification is *very*
particular about what information belongs in which column of the file.
There was 1 too many spaces between the atom name and the residue name,
and 2 too few spaces between the chain ID (A) and the residue number (1).
This caused the atomic coordinates to be in an unexpected place (i.e.,
they were shifted 1 character too far to the left), so they were not parsed
correctly. As a result, antechamber assigned the coordinates of every atom
to be 0, 0, 0.
Here is a link to the PDB spec:
http://deposit.rcsb.org/adit/docs/pdb_atom_format.html
I have attached a 'fixed' version of the PDB file which works with
AmberTools 12 (I highly suggest upgrading to AT 12).
