X-RAY DIFFRACTION 5.5 291 Index F6 0.2M Ammonium sulfate 0.1M Bis-Tris pH 5.5 25% PEG 3350. TrbrA.01480.a.WW4.PS38793 at 13.5 mg/mL. The C-terminal tail ~60 residues was disordered in each subunit. Residue Ser 71 in subunit A contained a large amount of density near the OG atom. This was modeled as a phosphoserine (SEP) although this is not a predicted phosphorylation site. 2mM AMP-PNP and 2mM MgCl2 added prior to crystallization. Prominent AMP-PNP density in subunit B but disorder in the phosphate portion. plate 20522 F6 drop 2, Puck: PSL-0904, Cryo: 80% crystallant + 20% glycerol
