Why do we need HETATM information?

When are they useful when processing proteins?

See HETATM at Proteopedia. There's many reasons these would be important. Just to name a few to get you started: A lot of post-translational modifications play critical roles in signaling and recruitment of other complexes. Metal ions and other co-factors play essential roles in function and catalysis.
