Crystallization and Preliminary Crystallographic Data for an FMN-dependent Nitroreductase from Escherichia coli B

An FMN-dependent nitroreductase enzyme isolated from Escherichia coli B has been crystallized in a form suitable for high-resolution structural analysis. The crystals belong to the tetragonal space group P4(1)2(1)2 or its enantiomorph P4(3)2(1)2 with cell parameters a = b = 57.74 A, c = 275.51 A and two molecules per asymmetric unit. Diffraction extends to beyond 1.9 A.
