Studies of proton pumping mechanism in BA3 type cytochrome oxidase of thermus thermophilus and CBB3 type cytochrome oxidase of vibrio cholerae
… site. According to the crystal structure of ba3 oxidase in T. thermophilus, two highly conserved residues, D372 and H376 which are located at the interface of subunit I and II of complex, form ion pairs with the A-propionate of active-site heme a3. A set of mutations of D372 and H376 are made and …

Characterizing the Role of the E. Coli Cytochrome Oxidase AppBCX During Intestinal Inflammation
… oxygen species (ROS) generated by the NADPH oxidase 1 (NOX1) at the epithelial interface serve as a local source of oxygen. Specifically, H2O2 deriving from epithelial NOX1, is detoxified via bacterial catalases to molecular oxygen. Facultative anaerobic bacteria can then respire this pool of …

Effect of citrate on the redox properties of cytochrome C and its kinetic and binding behaviour with cytochrome oxidase /
… ionic strength (30 mM) decreases the rate of cytochrome ~ reduction by ascorbate. This effect is also seen at both high (600 mM) and low (19 mM) ionic strengths, and the Kapp for citrate increases with increasing ionic strength. Citrate binds d both ferri -and ferrocytochrome ~, but with a …

Mobilização rápida de citocromo-oxidase por estimulação sensorial em córtex visual de gatos e primatas
The cytochrome oxidase fast mobilization was studied in twelve cats (Felis catus) and three monkeys (Cebus apella). Visual stimulus of low spatial frequency, with variations in colour and brightness and no spatial orientation allowed the observation of cytochrome oxidase-rich patches in flattened …

A macro- and micro-evolutionary investigation of African Camponotus ants
Camponotus than the cytochrome oxidase II gene, based on almost all measures of phylogenetic utility. The primary hypothesis proposed to account for this observation is that these two mitochondrial genes are evolving under different evolutionary constraints. Specifically, the cytochrome oxidase II …

A preliminary study of genetic variation within and among populations of Diaptomus leptopus (Copepoda: Calanoida) : a DNA sequence analysis of the Mitochondrial Cytochrome Oxidase I gene
… DNA sequence analysis of the mitochondrial cytochrome oxidase I gene may also be of use to study population structure. Thus, a study investigating the genetic variation within and among seven populations, distributed from Quebec to New York, of the freshwater copepod Diaptomus leptopus was …

Reorganization of Mitochondrial Genomes of Cms-S Maize Associated With Reversion to Fertility and Changes in Nuclear Background (S1 - S2 Plasmids, Cytochrome Oxidase I and Ii, Apocytochrome B)
The cms-S type of cytoplasmic male sterility in maize is characterized by the presence of linear mitochondrial plasmid-like DNAs, S1 and S2. Sequences homologous to S1 and S2 are also found in the main mitochondrial genomes of cms-S and normal fertile lines of corn.

Systematics of the Notonemouridae (Plecoptera) of southern Africa
… Additionalaims included an evaluation of the cytochrome oxidase subunit I gene as a molecular barcode in the Notonemouridae, a test of the monophyly of the genera, the construction of a phylogeny for the southern African Notonemouridae and the identification of clade synapomorphies.

Phylogeny of the Scarabaeini (Coleptera: Scarabaeidae)
… Molecular sequence data from mitochondrial Cytochrome Oxidase subunit I (1197 bp) and 16S ribosomal RNA (461bp) genes of 25 of these taxa were also obtained in an attempt to further resolve broad phylogenetic relationships inferred from morphology-based hypotheses of tribal evolution.

Genetic Structure of Amblyomma Cajennense (Acari: Ixodidae) Populations Based on Mitochondrial Gene Sequences
… 12S rDNA, control region (d-loop), and cytochrome oxidase II gene sequences of A. cajennense specimens collected in eight different localities. The results showed that our samples are grouped in five strongly supported monophyletic lineages, each corresponding to geographically or …

Phylogeography of Darlingtonea Kentuckensis and Molecular Systematics of Kentucky Cave Trechines
… DNA sequence data from the mitochondrial gene cytochrome oxidase subunit I (COI) was collected from one to four individuals from 27 populations, and patterns of phylogeography and population structure were inferred from COI haplotypes. A hierarchical analysis of molecular variance found low …

Mating Habits, Dispersal and Postglacial Range Expansion of Nigronia Serricornis (Say) (Megaloptera: Corydalidae)
… Using sequence data from a 630-base fragment of cytochrome oxidase I (COI), nested clade phylogeographical analysis (NCPA) was performed to determine the patterns of genetic diversity and the effects of post-glacial range expansion (PGRE). Haplotype diversity was significantly negatively …
