Crystals of NADPH:FMN oxidoreductase from Vibrio harveyi have been obtained and characterized by X-ray diffraction. This enzyme plays a role in the generation of light in luminescent bacteria by providing reduced FMN to luciferase. Large, high quality crystals were grown using polyethylene glycol 6000 at pH 7.0. They crystallize in the monoclinic space group P2(1) with cell dimensions a = 51.2 A, b = 85.9 A, c = 58.1 A, beta = 109.3 degrees, and diffract to 1.8 A. We expect two molecules per asymmetric unit. High resolution data sets have been recorded and a search is under way for heavy-atom derivatives.

D008970 Molecular Weight The sum of the weight of all the atoms in a molecule. Molecular Weights,Weight, Molecular,Weights, Molecular
D009247 NADH, NADPH Oxidoreductases A group of oxidoreductases that act on NADH or NADPH. In general, enzymes using NADH or NADPH to reduce a substrate are classified according to the reverse reaction, in which NAD+ or NADP+ is formally regarded as an acceptor. This subclass includes only those enzymes in which some other redox carrier is the acceptor. (Enzyme Nomenclature, 1992, p100) EC 1.6.

D011092 Polyethylene Glycols Polymers of ETHYLENE OXIDE and water, and their ethers. They vary in consistency from liquid to solid depending on the molecular weight indicated by a number following the name. They are used as SURFACTANTS, dispersing agents, solvents, ointment and suppository bases, vehicles, and tablet excipients. Some specific groups are NONOXYNOLS, OCTOXYNOLS, and POLOXAMERS.
