Dear Venkat,
Crystals are
categorized as extremely thin needles that are clustered and protrude around a
single nucleation site, and appear “fuzzy” in nature. I would particularly
recommend three different ways to optimize them, which I prioritized in
descending order:
1.
Ho Jun Lee,
Have you thought about differential scanning fluorimetry (Thermofluor)? With
this biophysical technique you can characterize protein-ligand interactions and
screen a wide variety of ligands using minimal concentration of ligand and
protein. All you need is a quantitative PCR machine
Feng Lei,
I would personally recommend slowing down the process of nucleation either by
lowering the temperature of crystallization or by utilizing Al's oil. These are
two powerful ways to slow the overall kinetics of crystallization. Here is a
relevant reference for you:

Danilo,
The protein cavity can be analyzed utilizing the program Voidoo ( Kleywegt GJ,
1994). This program uses an atomic-flattening algorithm based on a
3-dimensional grid to locate and delineate different cavities. A Van Der Waals
cavity can further be generated with a probe radius with a co
Dear Colleagues,
I have a question for all of you bioinformatics oriented structural biologists:
How do I predict the sites of protein-protein interactions between two
receptors that have been proven to interact biochemically but lack specific
details regarding proximity. This is not a straigh

Anita, In terms of the basics:Thermodynamic stability of a protein is related
to Gibbs Free Energy of unfolding. The Gibbs Free Energy is made of
temperature, enthalpy and entropy (Delta G = Delta H - T Delta S). At Delta G
equivalent to zero, the concentration of folded protein is equivalent
Jan,
I agree that the DTNB assay (Ellman's Reagent) can be used to quantify exposed
Cysteines. Alternatively, you could do site directed mutagenesis and mutate
significant amino acids responsible for the conformational change from the open
to the closed state, with hopes to lock the protein in
