X-RAY DIFFRACTION ? 298.15 NfEG12A-N18Y was concentrated to 10 mg/ml in a buffer containing 100 mM citric acid-Na2HPO4 (pH 7.2). both proteins were crystallized in a mother liquid with 0.1 M citrate (pH 5.0) and 16% (w/v) PEG 20000 using the hanging drop vapor diffusion method in 24-well plates. NfEG12A-N18Y crystals was transferred to a reservoir solution supplemented with 25% (v/v) ethylene glycol to grown. Obtained crystals were cryoprotected with 25% (v/v) 2-methyl-2,4-pentanediol. The crystals were mounted on a nylon loop and cooled immediately in liquid nitrogen prior to data collection.
