摘要

Fructan 1-exohydrolase IIa (1-FEH IIa), a plant enzyme involved in fructan breakdown, has been crystallized using the hanging-drop vapour-diffusion method at 277 K. The crystals are tetragonal, belonging to space group P4(1)2(1)2 or P4(3)2(1)2, with unit-cell parameters a=139.83, b=139.83, c=181.94 Angstrom. Calculation of the Matthews coefficient indicates there to be two or three molecules in the asymmetric unit. Synchrotron radiation was used to collect a complete native data set to a resolution of 2.35 Angstrom.
