title: Crystallization and preliminary X-ray diffraction analysis of a putative two-domain-type laccase from a metagenome.
abstract: A putative two-domain-type laccase retrieved from a metagenome was successfully crystallized using the sitting-drop vapour-diffusion method. Data were collected to a resolution of 1.7 A at 100 K using synchrotron radiation. The crystal belonged to space group P2(1)2(1)2(1), with unit-cell parameters a = 74.67, b = 100.95, c = 124.11 A. The self-rotation function showed the presence of a noncrystallographic threefold axis in the structure. The presence of one trimer in the asymmetric unit yielded a Matthews coefficient (V(M)) of 2.05 A(3) Da(-1) and a solvent content of 40%.
