Protein structure verification

Proteins are very simple molecules. They are linear chains of residues. And there are only 20 different residue types.

So far for the theory....

The practice is different:

These two points combined are the origin of "incorrect structures" and "weak points in generally correct structures". The check procedures in WHAT IF were written to help reduce this problem.

At the WHAT_CHECK pages you will find a more modern and updated explanation of today's WHAT_CHECK features.

WHAT IF I check my structure?
