Antibodies against synthetic peptides derived from the DNA sequence of human cytochrome c oxidase subunit II (COII) have been tested for their capacity to immunoprecipitate the whole enzyme complex. Antibodies against the COOH-terminal undecapeptide of COII (anti-COII-C), when incubated with a Triton X-100 mitochondrial lysate from HeLa cells pulse-labeled with [35S]methionine under conditions ...

To aid in identifying key predators of Proconiini sharpshooter species present in California, we developed and tested molecular diagnostic markers for the glassy-winged sharpshooter, Homalodisca coagulata (Say), and smoke-tree sharpshooter, Homalodisca liturata (Ball) (Homoptera: Cicadellidae). Two different types of markers were compared, those targeting single-copy sequence characterized ampl...

Four dinuclear CoII complexes have been synthesized and structurally characterized with the dinucleating ligand susan (susan=4,7-dimethyl-1,1,10,10-tetra(2-pyridylmethyl)-1,4,7,10-tetraazadecane) varying in exogeneous ligands: [(susan){CoII(CH3CN)2}2](PF6)4, [(susan){CoIICl}2](ClO4)2, [(susan){CoIIBr}2](ClO4)2, [(susan){CoII(μ-OH)CoII}](ClO4)3. The ions are six-coordinate CH3CN ligands five-coo...

The asymmetric unit of the title compound, [Co(NO3)2(C12H12N2S)2] n , contains a bis-(pyridin-3-ylmeth-yl)sulfane (L) ligand, an NO3- anion and half a CoII cation, which lies on an inversion centre. The CoII cation is six-coordinated, being bound to four pyridine N atoms from four symmetry-related L ligands. The remaining coordination sites are occupied by two O atoms from two symmetry-related ...

The Leishmania tarentolae cytochrome oxidase (EC 1.9.3.1) subunit II (COII) and maxicircle unidentified reading frame 3 (MURF3) mRNAs are edited internally by the addition of four and five uridine residues, respectively, which eliminate -1 and +1 reading frameshifts in the gene sequences. The editing events in COII are conserved in three kinetoplastid species, and those in MURF3 are conserved i...

Cyclic glyoxalcarbohydrazone[(1,2,4,5,8,9,11,12-octaazacyclotetradeca-5,7,12,14tetraene-3,10-dione) = (glyozalcarbzH)2] complexes of Ni II, PdII, CoII, ZnII and CdII of composition M (glyoxalcarbzH)2X2nH2O (M = Ni II, PdII, CoII,ZnII or CdII and X = Cl> , 1/2 SO4 -2 and n = 0,1 or 4) have been isolated by refluxing appropriate metal salts with glyoxal and carbohydrazide in requisite proportion ...

We assessed the in vitro toxicity of tenofovir (TFV) and compared it with those of zidovudine (AZT), didanosine (ddI), ritonavir (RTV), and lopinavir (LPV) alone and in combination in human renal proximal tubule epithelial cells (RPTECs). The cells were treated with various concentrations and combinations of the tested antiretrovirals for up to 22 days, and cytotoxicity was determined. In addit...

Due to their strict maternal inheritance in most animals and plants, mitochondrial genomes are predicted to accumulate mutations that are beneficial or neutral in females but harmful in males. Although a few male-harming mtDNA mutations have been identified, consistent with this 'Mother's Curse', their effect on females has been largely unexplored. Here, we identify COII(G177S), a mtDNA hypomor...

Bactrocera caudata is a pest of pumpkin flower. Specimens of B. caudata from the northern hemisphere (mainland Asia) and southern hemisphere (Indonesia) were analysed using the partial DNA sequences of the nuclear 28S rRNA and internal transcribed spacer region 2 (ITS-2) genes, and the mitochondrial cytochrome c oxidase subunit I (COI), cytochrome c oxidase subunit II (COII) and 16S rRNA genes....
