Abstract

Electrochemical oxidation of the hydrosulfide cluster [Fe4S4(SH)4]2- on gold, platinum or vitreous carbon in a methyl cyanide electrolyte leads to the growth of a conducting film. Spectroscopic and other evidence suggests that the film has cubane centres, predominately in the [4Fe4S]3+ oxidation state, which are linked by disulfide ligands to give an anionic array of [Fe4S4(S approximately)4]n- units. X-ray data suggests some long-range order in the electrode material. The polyferredoxin binds redox active cations consistent with an anionic array.

Crystallization and preliminary X-ray crystallographic analysis of p24, a component of the potato nuclear factor PBF-2.

The Solanum tuberosum (potato) nuclear factor PBF-2 is implicated in pathogen-induced expression of the pathogenesis-related gene PR-10a. Crystals of the DNA-binding component of PBF-2, p24, have been obtained at 277 K in 20 mM Tris-HCl pH 8.0. Recombinant protein with a His tag at its C-terminus was overexpressed in Escherichia coli in the presence and absence of selenomethionine and was purified using a combination of HiTrap affinity columns and gel-filtration chromatography. Crystals suitable for structural analysis were obtained for both native and selenomethionine-labelled proteins and yielded diffraction data at 100 K that were processed to 2.3 and 2.8 A resolution, respectively. The p24 protein crystals belong to space group P2(1)2(1)2(1), with unit-cell parameters a = 69.4 (69.1), b = 89.4 (90.5), c = 144.1 (144.3) A. The asymmetric unit contains four protomers, giving a crystal volume per protein mass (V(M)) of 2.23 A(3) Da(-1) and a solvent content of 45% by volume.

Crystallization and preliminary X-ray analysis of the DNA decamers d(CCGGATCCGG) and d(CCGGCGCCGG).

The DNA decamers d(CCGGATCCGG) and d(CCGGCGCCGG) have been crystallized for X-ray analysis in order to investigate the effects of changing the two central base pairs of the DNA fragment d(CCGGGACCGG). Previous studies have already demonstrated that the structure of the former DNA fragment contains a DNA Holliday junction. Crystals were obtained at 293 K by the hanging-drop vapour-diffusion technique using the Nucleic Acid Mini Screen. Over a period of two weeks, hexagonal plates appeared. For the DNA fragment d(CCGGATCCGG), the crystals belong to space group P3(1), with unit-cell parameters a = b = 33.54, c = 46.39 A, alpha = beta = 90, gamma = 120 degrees, and diffract to 2.2 A. In the case of the DNA fragment d(CCGGCGCCGG) the crystals belong to the space group C2, with unit-cell parameters a = 65.35, b = 24.07, c = 37.34 A, beta = 109.97 degrees, and diffract to 2.0 A.

Crystallization of PNMT, the adrenaline-synthesizing enzyme, is critically dependent on a high protein concentration.

Phenylethanolamine N-methyltransferase, PNMT, utilizes the methylating cofactor S-adenosyl-L-methionine to catalyse the synthesis of adrenaline. Human PNMT has been crystallized in complex with an inhibitor and the cofactor product S-adenosyl-L-homocysteine using the hanging-drop technique with PEG 6000 and lithium chloride as precipitant. A critical requirement for crystallization was a high enzyme concentration (>90 mg ml(-1)) and cryocrystallography was used for high-quality data measurement. Diffraction data measured from a cryocooled crystal extend to a resolution of 2.3 A. Cryocooled crystals belong to space group P4(3)2(1)2 and have unit-cell parameters a = b = 94.3, c = 187.7 A.
