Liquid–liquid diffusion crystallization improves the X-ray diffraction of EndoS, an endo-β-N-acetyl­glucosaminidase from Streptococcus pyogenes with activity on human IgG

A comparative study of vapor diffusion versus liquid–liquid diffusion methods used for the crystallization of EndoS is reported. X-ray diffraction data to 2.6 and 1.9 Å resolution were collected for wild-type endoglycosidase and glycosynthase constructs of EndoS, respectively.
