Re: [ccp4bb] Crystallisation of a extremly soluble protein

Sabine, There are protocols to modify surface residues that can help with crystallization, and make the protein less soluble. Unfortunately, I¹m drawing a blank on the details. I remember someone in Andrzej Joachimiak¹s group was working on this as a rescue approach for the structural genomics

Hello, Sabine. I believe the technique that Kendall is referring to is Surface Entropy Reduction, which involves replacing large, highly entropic residues on the surface of the protein with lower entropy residues to reduce the entropy shield and facilitate crystallization. Traditionally, the
