Autotracing of Escherichia coli acetate CoA-transferase alpha-subunit structure using 3.4 A MAD and 1.9 A native data.

ABSTRACT: The automation of protein structure determination is an essential component for high-throughput structural analysis in protein X-ray crystallography and is a key element in structural genomics. This highly challenging undertaking relies at present on the availability of high-quality native and derivatized protein crystals diffracting to high or moderate resolution, respectively. Obtaining such crystals often requires significant effort. The present study demonstrates that phases obtained at low resolution (>3.0 A) from crystals of SeMet-labeled protein can be successfully used for automated structure determination. The crystal structure of acetate CoA-transferase alpha-subunit was solved using 3.4 A multi-wavelength anomalous dispersion data collected from a crystal containing SeMet-substi
