Hi Anna,
Your structure and description remind me very much of our domain-swapped
crystal structure of trp repressor, also an infinite lattice.
One more example to add to the many that have been pointed out by others.

There are a variety of domain swapped crystal structures out there, but at

Hi Anna,
Interesting assembly. What is the function of your protein? Is it known if
your protein forms a fibril-like assembly in solution? Moreover, can your
crystal packing be indexed higher symmetry space group?

Ooh, that sounds nice! Could act as a bio-spring, releasable by dtt etc...

If we are to strictly adhere to polymer as describing "few", then were do
we stand with DNA/RNA being described as a polymer - a long polymer made up
from repeating units of nucleotides, as has been used in textbooks for
ages?! Is DNA/RNA too now a myriomer?

Okay, I wiki'd it, and according to them seems you're right: it says
they are "typically connected by covalent chemical bonds." So either
we revert to the etymological use of "polymer," or move onward to
"myriomer!" (assuming the cross-bred "multimer" is out of the
question!)

I love "myriomer," but what's wrong with boring old "polymer?"

Of course, "oligomer" (pure Greek) usually does that kind of job, but not in
this specific case, since oligo means few and in this case we have "endless"

I can only think of the neologism "myriomer" for this particular case, if
you want to stick to Greek. Myrioi can mean 1 or countle
I have been curious and suspicious for a long time about "multimer:" I
always assumed it to be a more homey substitute for "oligomer," as
there seems to me to be no difference in usage, and certainly not in
the etymological sense. I have often heard it used by non-experts who

Certainly it's interesting, but I think your description is inaccurate.
"Endless linear polymers" - Each monomer is a polymer, but a collection
of monomers is called a multimer, not a polymer.
I don't suppose there are any knots? That would be really interesting.

Wow, that's very cool! Can you divulge what the function of the
protein is? One thinks of some kind of mechanical spring...

Well - I guess you need to check the input mtz file.
do mtzdmo this.mtz and check that the columns you have selected are present and
have non-zero values. You need a FOM there.

Also, polydispersity is not great for crystallization but may not be

Dear colleagues,
This is a follow up to our earlier message, requesting prediction
targets for CASP10.
First THANK YOU to those who came forward with targets -- really much
appreciated, and has helped get this CASP off to a great start. We now
have over 70 targets released.
Second, please
