Crystallization and X-ray diffraction studies of cellobiose phosphorylase from Cellulomonas uda.

ABSTRACT: Disaccharide phosphorylases are able to catalyze both the synthesis and the breakdown of disaccharides and have thus emerged as attractive platforms for tailor-made sugar synthesis. Cellobiose phosphorylase from Cellulomonas uda (CPCuda) is an enzyme that belongs to glycoside hydrolase family 94 and catalyzes the reversible breakdown of cellobiose [beta-D-glucopyranosyl-(1,4)-D-glucopyranose] to alpha-D-glucose-1-phosphate and D-glucose. Crystals of ligand-free recombinant CPCuda and of its complexes with substrates and reaction products yielded complete X-ray diffraction data sets to high resolution using synchrotron radiation but suffered from significant variability in diffraction quality. In at least one case an intriguing space-group transition from a primitive monoclinic to a primiti
