9) superimposes very well on the crystallographic structure: the root-mean-square distance of the Cα atoms between the two structures amounts to about 1 Å [102]. The average length of the 19 amphipathic β-strands is about 10 residues and the average inclination of the β-strands ...
The role of Ca2+as Lewis acid by coordinating neutral and radical intermediates (oxygen atoms act as Lewis bases) seems plausible. The formation of the glycosidic bond between ribose and a nucleobase would result from the reaction of a cyclic free radical derived from ribose with a neutral nucle...

oriented in different directions relative to the surface. Normally the surface looks uniform, because the orientation of the underlying crystal zone doesn't have any effect on how light is reflected, probably because right at the very surface the atoms are disordered by their interaction with air ...
