Materials and MethodsCrystal Growth. The Tyr240—* Phe mutant of aspartate carbamoyltransferase, prepared and purified as previously described (Middleton & Kantrowitz, 1986), was stored at-20C as a 25 mg/mL solution in 1: 1 (v/v) glycerol/storage buffer [40 mM K2P04, 2.0 mM/J-mercaptoethanol, 0.2 mM EDTA (pH 7.0)] and was dialyzed for 24 h against storage buffer prior to crystallization. The enzyme solution was diluted to 20 mg/mL with storage buffer and filtered through a 0.22-^ m filter (Millipore GV). Crystallization was effected by dialyzing the enzyme solution, at room temperature, against a buffer of 40 mM sodium citrate, 1.0 mM/j-mercaptoethanol, 0.2 mM EDTA, and 1.0 mM CTP with the pH adjustedto 5.8 by HCI. Typically, hexagonal plates in the space group
