Abstract: Background: Hemiscorpius lepturus is a medically important scorpion found along the Iranian borders, especially near to Khuzestan Province in the south-west of Iran. This is the only non-buthid scorpion which is potentially lethal in southern Iran and is responsible for severe dermonecrotic scorpionism. OBJECTIVES: In this study, DNA fragment of the mitochondrial cytochrome c oxidase ...

the identification of the efficiency of some mtdna genes of mus musculus species complex (house mouse) for biosystematics research was studied in this approach. recent studies have made use of different mitochondrial genes including nadh dehydrogenase genes, cytochrome b gene, cytochrome oxidase genes, d-loop region and whole mtdna genome to study the house mouse species. usage of each of these...

The effects of digitonin and tocopherol on bovine heart reduced diphosphopyridine nucleotideand succinate-cytochrome c reductases and cytochrome c oxidase have been studied with the following results. 1. Low concentrations of digitonin stimulate succinateand DPNH-cytochrome c reductase and cytochrome c oxidase. Higher concentrations of digitonin completely inhibit cytochrome c reductases, while...

The study of liver microsomal electron transport and drug metabolism activities involving NADPH-cytochrome c reductase has been performed using immunochem ical techniq ues ( I -4). This approach has been particularly valuable in establishing the role of this flavoprotein in the reduction of microsomal cytochrome P-450 and, thus, in the metabolism of drugs (2, 3). The existence of NADPH-cytochro...

This is the first report for Iran of Dolichogenidea laevigata (Ratzeburg, 1848) (Hymenoptera: Braconidae: Microgastrinae) parasitizing larvae European leaf roller Archips rosana (Linnaeus, 1758) (Lepidoptera: Tortricidae). The parasitized A. were obtained from different host plants. occurrence D. and its diagnosis are presented. In addition, a full DNA barcode (the mitochondrial cytochrome oxid...

The effects of digitonin and tocopherol on bovine heart reduced diphosphopyridine nucleotideand succinate-cytochrome c reductases and cytochrome c oxidase have been studied with the following results. 1. Low concentrations of digitonin stimulate succinateand DPNH-cytochrome c reductase and cytochrome c oxidase. Higher concentrations of digitonin completely inhibit cytochrome c reductases, while...

The membranes from Corynebacterium glutamicum cells contain a hydrophobic di-haem C protein as the cytochrome c subunit of the new type of cytochrome bc complex (complex III in the respiratory chain) encoded by the qcrCAB operon [Sone, N., Nagata, K., Kojima, H., Tajima, J., Kodera, Y., Kanamaru, T., Noguchi, S. & Sakamoto, J. (2001). Biochim Biophys Acta 1503, 279-290]. To characterize complex...

Since yeast is amenable to mitochondrial transformation, designed mutations can be introduced in the mitochondrially encoded subunits of the respiratory complexes. In the present work, six mutations have been introduced by the biolistic method into yeast (Saccharomyces cerevisiae) cytochrome oxidase subunits I and III. The effects of these mutations on respiratory growth competence, cytochrome ...

Plant mitochondria unlike their animal counterpart have some unique features with highly branched respiratory chain. The present work was undertaken in order to investigate the effect of loss/dysfunction of plant mitochondrial complex I on the relative flux of electrons through alternative oxidase (AOX) and cytochrome oxidase. Loss of a major subunit of mitochondrial complex I in cytoplasmic ma...
