X-RAY DIFFRACTION 5.6 292 A racemic mixture of L-Aureocin A53 and D-Aureocin A53 at 40 mg/mL concentration was mixed 1:1 with 0.2 M ammonium acetate, 0.2 M sodium citrate and 29% PEG 4000 v/v precipitant condition, pH 5.6 in a 1 microlitre sitting drop. The crystal was soaked with sn-glycerol-3-phosphate (334 mM in the precipitant solution) at 1:1 v/v for 24 hours (50 equivalents). Crystals were submerged in 20% PEG 400 in the precipitant solution as cryoprotectant and flash frozen in liquid nitrogen during harvesting.
