Crystallization and preliminary X-ray study of alkaline beta-mannanase from the alkaliphilic Bacillus sp. N16-5

Acta Crystallogr Sect F Struct Biol Cryst Commun. 2008 Oct 1;64(Pt 10):957-9. doi: 10.1107/S1744309108028571. Epub 2008 Sep 30.

Abstract

The catalytic domain of an alkaline beta-mannanase from the alkaliphilic Bacillus sp. N16-5 has been expressed and purified. The recombinant enzyme was crystallized using the hanging-drop vapour-diffusion method at 298 K. X-ray diffraction data were collected to 1.6 A resolution. The crystal belonged to the orthorhombic space group P2(1)2(1)2(1), with unit-cell parameters a = 59.03, b = 63.31, c = 83.34 A. Initial phasing was carried out by molecular replacement using the three-dimensional structure of a mannanase from the alkaliphilic Bacillus sp. JAMB602 as a search model.
