Remembrances of Professor G . N . Ramachandran ( 1922 – 2001

Editor’s note: Few scientists contribute an idea of such clarity and power that it appears in all the discipline’s textbooks and bears the author’s name. For the contribution to be relevant and universally employed almost forty years after it first appeared is even less common. Structural biology lost the author of such an idea with the death of G.N. Ramachandran, whose picture appears on the c...

Chemical crystallography and crystal engineering

Today, there is very little doubt that chemistry owes as much to crystallography as crystallography does to chemistry. This mutual synergy defines modern chemical crystallography.

Crystallography is more than crystal structures

New developments in neutron and synchrotron science and technology are discussed.

Crystallography and protein-protein interactions: biological interfaces and crystal contacts.

Crystallography is commonly used for studying the structures of protein-protein complexes. However, a crystal structure does not define a unique protein-protein interface, and distinguishing a 'biological interface' from 'crystal contacts' is often not straightforward. A number of computational approaches exist for distinguishing them, but their error rate is high, emphasizing the need to obtai...
