PubMed Abstract:
The gene product of At3g22680 from Arabidopsis thaliana codes for a protein of unknown function. The crystal structure of the At3g22680 gene product was determined by multiple-wavelength anomalous diffraction and refined to an R factor of 16.0% (Rfree = 18.4%) at 1.60 A resolution. The refined structure shows one monomer in the asymmetric unit, with one molecule of the non-denaturing detergent CHAPS {3-[(3-cholamidopropyl)dimethylammonio]-1-propane sulfonate} tightly bound. Protein At3g22680 shows no structural homology to any other known proteins and represents a new fold in protein conformation space.
