The TcDHFR-TS-C-448-NDP-dUMP crystal belonged to space group C2221 with two molecules per asymmetric unit and diffracted to 2.37 Å resolution. The TcDHFR-TS-CYC, TcDHFR-TS-CYC-NDP and TcDHFR-TS-Q-8-NDP crystals belonged to space group P21 with four molecules per asymmetric unit and diffracted to 2.1, 2.6 and 2.8 Å resolution, respectively. Crystals belonging to the two different space groups were suitable for structure determination. © 2009 International Union of Crystallography.
