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 ?

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
symmet

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
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
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

Following up on the original post, I was recently asked to give a popular
