Evolutionary Conservation Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf. Publication Abstract from PubMedWe developed an Escherichia coli cell-based system to generate proteins containing 3-iodo-l-tyrosine at desired sites, and we used this system for structure determination by single-wavelength anomalous dispersion (SAD) phasing with the strong iodine signal. Tyrosyl-tRNA synthetase from Methanocaldococcus jannaschii was engineered to specifically recognize 3-iodo-l-tyrosine. The 1.7 A crystal structure of the engineered variant, iodoTyrRS-mj, bound with 3-iodo-l-tyrosine revealed the structural basis underlying the strict specificity for this nonnatural substrate; the iodine moiety makes van der Waals contacts with 5 residues at the binding pocket. E. coli cells expressing iodoTyrRS-mj and the suppressor tRNA were used to incorporate 3-iodo-l-tyrosine site specifically into the ribosomal protein N-acetyltransferase from Thermus thermophilus. The crystal structure of this enzyme with iodotyrosine was determined at 1.8 and 2.2 A resolutions by SAD phasing at CuKalpha and CrKalpha wavelengths, respectively. The native structure, determined by molecular replacement, revealed no significant structural distortion caused by iodotyrosine incorporation.
