BACKGROUND Buparvaquone (BW 720C) is the major hydroxynaphtoquinone active against tropical theileriosis (Theileria annulata infection). Previous studies showed that buparvaquone, similarly to others hydroxynaphtoquinone, probably acts by binding to cytochrome b (cyt b) inhibiting the electron transport chain in the parasite. Several observations suggested that T. annulata is becoming resistant...

Mitochondrial cytochrome c is a water-soluble protein in the intermembrane space which catalyzes electron transfer from the cytochrome bc1 complex to the terminal oxidase cytochrome aa3. In Bradyrhizobium japonicum, a gene (cycM) which apparently encodes a membrane-anchored homolog of mitochondrial cytochrome c was discovered. The apoprotein deduced from the nucleotide sequence of the cycM gene...

designated C115 and C117, are inherited as gene differences. C115 and mi-3 both have an excess of cytochrome c but not as great as in poky and both, like poky, are deficient in cytochrome a. The content of cytochrome b is normal in mi-3 and low in C15 but not as low as in poky. Cytochromes a and c have not been detected in C117 but there is an excess of cytochrome b. The three strains grow more...

Reduced oxygenation of a variety of cells results in transcriptional upregulation of several genes, including the hematopoietic hormone erythropoietin, the angiogenic vascular endothelial growth factor (VEGF), and glycolytic enzymes such as aldolase. Recently, the heme protein cytochrome b558 of the nicotinamide adenine dinucleotide phosphate (NADPH) oxidase complex has been proposed as a key c...

Abstract Australian arboreal mammals are experiencing significant population declines, particularly due to land clearing and resulting habitat fragmentation. The squirrel glider, Petaurus norfolcensis , is a threatened species in New South Wales, with stronghold the Lake Macquarie Local Government Area (LGA) where fragmentation urbanization an ongoing problem for conservation. Here we report on...

Rodents from the subfamily Gerbillinae Gray, 1825, are an important component of small fauna in arid and desertic regions Africa Asia. Among this group rodents, Sundevall’s jird, Meriones crassus, is one most widespread desert species, found countries ranging Morocco to Pakistan. In study, we sequenced cytochrome b gene mitochondrial DNA two specimens captured Morocco, constituting first geneti...
