The presence of cytochrome c oxidase subunits and the association of these subunits with each other was studied in a heme-deficient Saccharomyces cerevisiae mutant. This mutant had been isolated by Gollub et al. (1977) J. Biol. Chem. 252, 2846-2854) and had been shown lack delta-aminolevulinic acid synthetase. When grown in the absence of heme or heme precursors, the mutant is respiration-defic...

In the preceding paper the oxidation of substrates by “indophenol oxidase” was demonstrated to be a joint action of cytochrome and cytochrome oxidase. It was further shown that with a given amount of oxidase the velocity of hydroquinone oxidation reached a maximum as the amount of added cytochrome was increased. The latter fact immediately suggested the probability that the rapid aerobic oxidat...

A large-type sexannulate leech species, Orobdella ibukifukuyamai sp. nov. , from Kii-Oshima Island, Japan, is described based on morphologic and molecular data. Phylogenetic analyses using nuclear 18S rRNA, 28S histone H3, mitochondrial cytochrome c oxidase subunit I, tRNA Cys Met 12S Val 16S Leu NADH dehydrogenase 1 markers showed that O. formed a clade with the okanoi Nakano, 2016 yamaneae oc...

As the primary and preferred energy source of normal colonic epithelial cells, fatty acids may play a unique role in the differentiation and physiology of these cells. We have shown that expression levels of COXIII, a mitochondrial gene encoding one of the 13 subunits of cytochrome c oxidase, are abnormally low in colon tumors and colonic tissue at genetic risk for developing tumors but increas...

Vectorially oriented monolayers of yeast cytochrome c and its bimolecular complex with bovine heart cytochrome c oxidase have been formed by self-assembly from solution. Both quartz and Ge/Si multilayer substrates were chemical vapor deposited with an amine-terminated alkylsiloxane monolayer that was then reacted with a hetero-bifunctional cross-linking reagent, and the resulting maleimide endg...

The electron-transfer reactions of cellobiose oxidase (CBO) have been investigated by conventional and by rapid-scan stopped-flow spectroscopy at pH 6.0. Analysis of the absorbance/time/wavelength matrix by Singular Value Decomposition (SVD) confirms earlier studies showing that cellobiose rapidly reduces the flavin group (7.7 s-1; cellobiose, 100 microM) which in turn slowly (0.2 s-1) reduces ...

The genus Bionychiurus Pomorski, 1996 is not recorded from India so far. A new species nominated as tamilensis sp. n. described the Nilgiri Hills in Western Ghats. possess a dorsal pso formula 32/133/33,343 and ventral 11/011/11,121. similar to changbaiensis, B. normalis, oblongatus reported China Korea. 658 bp mitochondrial cytochrome oxidase subunit I DNA region (COX1) of was sequenced for it...

Terranigra kosovica Radoman, 1978, was known from four localities in Kosovo. The monotypic genus described on the basis of genital morphology. We collected T. at a new locality, about 40 km its type locality. shell morphology, as well soft part morphology and anatomy were identical to that by Radoman. molecular markers mitochondrial cytochrome oxidase subunit I (COI) nuclear histone (H3) resolv...

The cytochrome c oxidase Cox2 has been purified from native membranes of the hyperthermophilic eubacterium Aquifex aeolicus. It is a cytochrome ba(3) oxidase belonging to the family B of the heme-copper containing terminal oxidases. It consists of three subunits, subunit I (CoxA2, 63.9 kDa), subunit II (CoxB2, 16.8 kDa), and an additional subunit IIa of 5.2 kDa. Surprisingly it is able to oxidi...

Two new species of the genus Cratospila Foerster, 1863 (Braconidae: Alysiinae), albosignata sp. nov. and C. longivena , are described illustrated. In addition, DNA barcode region mitochondrial cytochrome c oxidase subunit I ( COI ) both has been sequenced with three previously albifera luteocephala syntoma ). Alysia ponerola Papp, 2009 which was recorded from North Korea is transfered in (Papp,...
