Notes:
Three β-mannanase isoforms were isolated from the supernatant of a thermophilic actinomycete culture from Thermomonospora fusca KW3. Two of the isoforms (Q1, Q 1.1) were crystallized by the hanging-drop method at room temperature using ammonium sulfate as a precipitant. The isoforms form rod-shaped colorless crystals. Both belong to the orthorhombic space group P212121. The cell dimensions are a = 46.7, b = 61.1, and c = 128.2 Å for isoform Q1, and a = 43.8, b = 46.2, and c = 132.8 Å for isoform Q1.1. The asymmetric unit of either isoform contains one mannanase molecule. Native data have been collected to 2.2 Å resolution for Q1 and to 1.65 Å resolution for Q1.1 using synchrotron radiation.
