Crystals were initially identified in the Morpheus II screen condition G5 (15% PEG 3K, 20% 1,2,4 butanetriol, 1% NDSB-256, 20 mM arginine, 20 mM threonine, 20 mM histidine, 20 mM hydroxylysine, 20 mM trans-4-hydroxy-L-proline, and buffered by 50 mM BES and 50 mM triethanolamine at pH 7.5). Seeds were generated from this condition and used for random microseed matrix screening (rMMS) using a protein concentration of 10-12 mg/ml. Final crystals were identified in the Index HT screen condition H2 (0.2 M Potassium sodium tartrate tetrahydrate, 20% w/v Polyethylene glycol 3,350). Crystals were cryoprotected by transfer to a drop containing a 4:1 ratio of precipitant ethylene glycol |
