Crystal structure of gene locus At3g16990 from Arabidopsis thaliana.

Introduction. The Center for Eukaryotic Structural Genomics is dedicated to determining the structures of novel proteins from eukaryotic organisms. Open reading frames are scored using thirteen different categories (i.e. new fold prediction, solubility prediction, small percentage of low complexity sequence, etc.) and then ranked to indicate their suitability for study bynuclearmagnetic resonance (NMR) or X-ray crystallography.Gene locusAt3g16990 fromArabidopsis thaliana was given a suitable score for study, with the only major demerits being a large cysteine residue count, a moderate new fold prediction and a predicted low expression based on gene chip results. Here, we report the crystal structure of the protein fromArabidopsis thaliana gene locus At3g16990 as determined by single wavelength anomalous dispersion (SAD) phasing.
