title: Crystallization of Photobacterium leiognathi non-fluorescent flavoprotein, an unusual flavoprotein with limited sequence identity to bacterial luciferase.
abstract: Single crystals of the non-fluorescent flavoprotein (NFP) purified from Photobacterium leiognathi strain S1 have been grown from ammonium sulphate solutions using the hanging drop vapour diffusion technique. The crystals grow as thin (0.06 mm) plates and belong to the orthorhombic space group C222(1): a = 57.06(3) A, b = 92.41(6) A, c = 99.52(6) A. There is one NFP monomer per asymmetric unit and crystals diffract to 2.2 A spacings on film. A complete native data set to 2.5 A resolution has been collected on a San Diego Multiwire Detector system at the University of Alberta and a heavy-atom derivative search is presently in progress.
