Does that CA have a metal center (I think they all do)? If so, doesn't the
citrate compete for the metal?

Dear Dave,
many methods articles mention a small set of commonly used proteins. E.g.
Mueller et al, "Optimal fine phi-slicing for single-photon-counting
pixel detectors", Acta Cryst D68, p42-56 list Insulin, Lysozyme,
Thaumatin, and Thermolysin;
Nana
My suggestions would be to look up citations for thaumatin and glucose
isomerase. If I remember correctly, both of them form well diffracting
crystals within a short period of time. I think you can also buy the
purified protein from a vendor. Perhaps you could also try the good old
lysozyme.

Hi David,
You could try the Glucose Isomerase supplied by Hampton. It crystallizes
under a number of conditions, details of which you can find in their manual.

I'm at an undergrad only school, and every 2 years I teach a class in
protein crystallography. This year I'm being super ambitious, and I'm
going to take a class of 16 to the synchrotron for data collection.
