Abstract:
Does the crystal structure of a protein accurately represent its structure in solution? Or does the crystallization process perturb the structure significantly? Although aware of the problem, most crystallographers would argue that the highly solvated and weakly held lattice in protein crystals is, in general, unlikely to shift ordered parts of the molecule. In the case of conformationally flexible proteins, however, there is the possibility that one form might be favoured over another. Several lines of evidence suggest that this might be the case for the crystal structure of liganded Hb, although conflicting data exist.

Metal-Ligand Bonds
In these complexes, transition metals form coordinate covalent bonds, a kind of Lewis acid-base interaction in which both of the electrons in the bond are contributed by a donor (Lewis base) to an electron acceptor (Lewis acid). The Lewis acid in...

Ligand Binding Sites
Protein-ligand interactions are quite specific; even though numerous potential ligands surround a cellular protein at any given time, only a particular ligand can bind to that protein. Moreover, a ligand binds only to a dedicated area on the surface of the protein, known as the...
