Getting the chemistry right: protonation, tautomers and the importance of H atoms in biological chemistry
There are more H atoms than any other type of atom in an X-ray crystal structure of a protein–ligand complex, but as H atoms only have one electron they diffract X-rays weakly and are ‘hard to see’. The positions of many H atoms can be inferred by our chemical knowledge, and such H atoms can be adde...
