Reactive oxygen species (ROS) are implicated inthe pathogenesis of chemically induced gastric mucosalinjury. We have investigated the effects of ethanol,hydrochloric acid (HCl), and sodium hydroxide (NaOH) on: (1) enhanced production of ROSincluding

The disposition of the heme groups in cytochrome cd1 oxidase from Pseudomonas aeruginosa is studied by emission spectroscopy. This protein of molecular weight 120 000 is composed of two monomers each with a heme c and a heme d1. It has been shown by

The dichroism for photochemical attachment of a psoralen derivative to Mg2+ -stabilized chromatin fibres is used to deduce the orientation of nucleosomal disks and linker DNA in the 30-nm fibre. The new technique of photochemical electric dichroism s

On the basis of redox kinetic studies, Rosen and Pecht [Rosen, P. & Pecht, I. (1976) Biochemistry 15, 775-786] postulated a slowly attained (approximately equal to 0.1 sec) conformational equilibrium between two forms of reduced azurin from the bacte

The irreversible thermal denaturation of cytochrome cd1 oxidase from P. aeruginosa as a function of the oxidation-reduction states of its hemes was observed with a differential scanning calorimeter. Upon full reduction of the four hemes, the apparent

We have used photochemically detected linear dichroism to measure the separate average angular orientations of nucleosomes and linker DNA in 30-nm chromatin fibers of varying linker size (20-80 base pairs). Our results indicate that the average tilt
