LITERATURE
in complex with a dimer of alpha-2,9-linked sialic acid, hanging drop vapor diffusion method, using 6% (w/v) PEG3350, 70 mM CHES buffer, pH 9.5 and 70 mM SrCl2
crystal structure of the catalytic domain of endoN from caliphate K1F reveals a functional trimer, folding is mediated by an intramolecular C-terminal chaperone domain

hanging drop vapor diffusion method, using 16% (w/v) PEG 8000, 0.1 M Tris-HCl pH 7.2, 3% (v/v) 2-propanol
-
in complex with oligomeric sialic acid, 1.9 A resolution
wild type endoNF cocrystallized with oligomeric sialic acid and mutant enzymes H350A and R647A are crystallized by the hanging drop vapor diffusion method, using
