Abstract: The non-ATPase subunit Nas6, which is the human orthologue of gankyrin, was co-expressed with the C-terminal domain of the ATPase subunit Rpt3 of the yeast 26S proteasome in Escherichia coli, purified to near-homogeneity and crystallized using the hanging-drop vapour-diffusion method- The protein crystallized in space group P2-1-, with unit-cell parameters a = 60-38, b = 100-22, c = 72-20 A, beta = 94-70 degrees and with three Nas6-Rpt3C molecules per asymmetric unit- The crystal diffracted to beyond 2-2 A resolution using synchrotron radiation-
