Crystallization and preliminary X-ray crystallographic analysis of recombinant β-mannosidase from Aspergillus niger

β-Mannosidase from Aspergillus niger was crystallized in the presence of D-mannose and the crystal diffracted to 2.41 Å resolution. The crystal belonged to the space group P1 with unit-cell parameters a= 62.37, b = 69.73, c = 69.90 Å, α = 108.20, β = 101.51, γ = 103.20°.
