Abstract
The cytochrome d complex is one of two membrane-bound terminal oxidases of the Escherichia coli aerobic respiratory chain. Previous studies have shown that this enzyme reconstituted into proteoliposomes rapidly oxidizes ubiquinol-8 as well as the soluble homologue, ubiquinol-1, and that quinol oxidase activity is accompanied by the formation of a transmembrane H+ electrochemical gradient. The enzyme also oxidizes the artificial reductant, N,N,N',N'-tetramethyl-p-phenylenediamine (TMPD) with the generation of a H+ electrochemical gradient. In this work, it is established that trypsin digestion of the purified cytochrome d complex cleaves subunit I while subunit II is unaffected. Proteolysis of subunit I is correlated with loss of ubiquinol-8 and ubiquinol-1 oxidase activities. Trypsin digestion has no effect on TMPD oxidase activity. The cytochrome d complex is concluded to possess three distinct active sites for 1) ubiquinol oxidation, 2) TMPD oxidation, and 3) oxygen binding and reduction. Data also suggest that both sites of ubiquinol and TMPD oxidations are located on the periplasmic side of the E. coli membrane while the site of oxygen reduction is on the opposite side.

Abstract
The cytochrome o terminal oxidases from the bacteria Vitreoscilla and Escherichia coli are structurally and functionally related. They have similar optical spectra, both exhibit ubiquinol-1 oxidase activity and are inhibited similarly. Both enzymes contain four subunits by SDS-polyacrylamide gel electrophoresis analysis and contain protoheme IX and Cu2+ prosthetic groups. Antibodies raised against the oxidase purified from E. coli crossreact with the Vitreoscilla oxidase.

Abstract
The effects of and recovery from luminal ethanol (0%-100%) were assessed in the in vitro chambered frog gastric mucosa. At concentrations of 5%-10%, the potential difference decreased during exposure, but recovered after washout. No gross or light microscopic changes were observed. During exposure to 20%-40% ethanol, potential difference and short circuit current decreased and resistance increased, with only partial recovery after removal of the alcohol. Acid secretion ceased at 20% ethanol and alkalinization of the luminal solution was observed at greater than or equal to 30% ethanol. Microscopy of this group showed discharge of mucus, separation of oxynticopeptic cells from the basal lamina, and slough of surface epithelium. At 60%-100% ethanol, potential difference and short circuit current decreased and resistance increased markedly but there was no recovery. Microscopy showed changes similar to those of the intermediate group (20%-40%), except that surface epithelial cells were fixed to the basal lamina rather than sloughing. The morphologic effects of 100% ethanol in vivo were similar to those in vitro. Pretreatment with 10(-5) M 16,16-dimethyl prostaglandin E2 did not prevent either the electrophysiologic or the histologic changes caused by 20% and 30% ethanol. We conclude that there is a gross discrepancy between the functional and morphologic findings after high concentrations of luminal ethanol.

Abstract
The aerobic respiratory chain of Escherichia coli contains two terminal oxidases, the cytochrome o complex and the cytochrome d complex. These both function as ubiquinol-8 oxidases and reduce molecular oxygen to water. Electron flux is funneled from a variety of dehydrogenases, such as succinate dehydrogenase, through ubiquinone-8, to either of the terminal oxidases. A strain was examined which lacks the intact cytochrome d complex, but which overproduces one of the two subunits of this complex, cytochrome b558. This cytochrome, in the absence of the other subunit of the oxidase complex, does not possess catalytic activity. It is shown that the extent of reduction of cytochrome b558 in the E. coli membrane monitors the extent of reduction of the quinone pool in the membrane. The activity of each purified oxidase was examined in phospholipid vesicles as a function of the amount of ubiquinone-8 incorporated in the bilayer. A ratio of ubiquinol-8:phospholipid as low as 1:200 is sufficient to saturate each oxidase. The maximal turnover of the oxidases in the reconstituted system is considerably faster than observed in E. coli membranes, demonstrating that the rate-limiting step in the E. coli respiratory chain is at the dehydrogenases which feed electrons into the system.
