All the refugees after Brexit, and the latest in the "most
powerful"country, can seek refuge in India. Since several millennia we have
offered- and continue to offer total detachment from anything and
everything happening around oneself, mental peace and ultimate pleasure in
the spirituality. I gue
Several years ago, we had an interesting case, where the molecule - a
tetramer, did not possess the classical 222 or 4-fold symmetry.
Rather, two monomers were related by a 2-fold, and other two monomers were
related by yet another 2-fold. Ofcourse, the confirmation that it was
indeed a tetramer w
I agree with Ethan.
In philosophy, NMA is a useful analysis to study low frequency collective
motions. That is true by taking a stand-alone structure and explore such
motions of biological interest. Domain motions in the crystallographic
environment need not necessarily correspond to those of

Following up on the original post, I was recently asked to give a popular
account of 100 years of X-ray diffraction in about 6 minutes :) This was
broadcast on All India Radio from New Delhi on the 12th April across India,
but the conservative estimates suggest that no more than 5 persons heard it
As a person who wears two hats- "we- the crystallographers" and "they- the
bioinformaticians" it is interesting to see that the world can be divided
by one of the most trivial issues- coordinate formats! Enjoying the debate

Welljust to add, it has been our contention that many of the metal ions
have been modelled as waters in several structures- due perhaps to the lack
of sufficiently high resolution data. We published some of the potential
metal binding sites in many structures a few years ago:
Proteins. 2008 M
Phosphoserine ?

One of the early references for mFo- nFc is:
Vijayan, *Acta Cryst.* (1980). A*36*, 295-298
You may also like to read the book on Fourier transforms in crystallography
by Ramachandran and Srinivasan.

Peanut lectin, when we solved the structure in the 90's, had a very unusual
non-symmetric tetramer. Till we solved the structure, there were examples
only of symmetric tetramers 222 (say, ConA), or 4 (e.g. Neuraminadase) in
the literature. Peanut lectin had two dimers, each with a two-fold
