Dilution was done with protein buffer. The mixture was added to crystallization liquid 1 to 1 and the mixture was pipetted on siliconized glass disks and sealed on top of a reservoir of crystallization liquid for hanging drop crystallization at 12 degrees Celsius. The crystallization liquid has the following composition: 100 mM Bicine at pH 6.6, 200 mM NaCl, 20 mM putrescine, 1 mM TCEP, 1 mM inositol hexa phosphate (phytic acid) and 45 % pentaerythritol propoxylate (5/4 PO/OH)
