Abstract:
A novel xyloglucan-specific exo-beta-glycosidase, oligoxyloglucan reducing-end specific cellobiohydrolase (OXG-RCBH), recognizes the reducing end of oligoxyloglucan and releases two glucosyl residue segments from the main chain. OXG-RCBH was crystallized by the hanging-drop vapour-diffusion method with polyethylene glycol 3000 and polyethylene glycol 400 as precipitants. The crystals belong to the orthorhombic space group P2(1)2(1)2(1), with unit-cell parameters a = 61.0, b = 146.9, c = 211.9 A. The crystals diffract to a resolution of 2.2 A and are suitable for X-ray structure analysis.
