Characterization of crystals of genetically engineered human manganese superoxide dismutase

Abstract The genetically engineered human manganese superoxide dismutase crystallizes in space group P 2 1 2 1 2 with a = 75·51 A , b = 79·00 A , c = 67·95 A . At room temperature the crystals are not stable against radiation, so we cooled them to 90 K and collected a data set to 3 A resolution at this temperature.
