c-Type cytochromes in Pelobacter carbinolicus.
Previous studies failed to detect c-type cytochromes in Pelobacter species despite the fact that other close relatives in the Geobacteraceae, such as Geobacter and Desulfuromonas species, have abundant c-type cytochromes. Analysis of the recently completed genome sequence of Pelobacter carbinolicus revealed 14 open reading frames that could encode c-type cytochromes. Transcripts for all but one...
متن کاملCyc2p, a membrane-bound flavoprotein involved in the maturation of mitochondrial c-type cytochromes.
Mitochondrial apocytochrome c and c1 are converted to their holoforms in the intermembrane space by attachment of heme to the cysteines of the CXXCH motif through the activity of assembly factors cytochrome c heme lyase and cytochrome c1 heme lyase (CCHL and CC1HL). The maintenance of apocytochrome sulfhydryls and heme substrates in a reduced state is critical for the ligation of heme. Factors ...
متن کاملLack of distinction between Nitrobacter agilis and Nitrobacter winografskyi.
No adequate criteria were established to distinguish between Nitrobacter agilis and N. winogradskyi. However, very gentle preparative techniques permitted demonstration of flagella in N. agilis.
متن کاملDeoxyribonucleic acid in Nitrobacter carboxysomes.
Carboxysomes were isolated from Nitrobacter winogradskyi and Nitrobacter agilis. The icosahedral particles contained double-stranded deoxyribonucleic acid (DNA). In the presence of ethidium bromide and cesium chloride, the particle-bound DNA had a buoyant density of rho 25 = 1.701 g/cm3. Electron microscopy revealed the DNA to be a 14-micron circular molecule.
متن کاملConcentration and function of membrane-bound cytochromes in cyanobacterial heterocysts.
Membranes isolated from heterocysts and vegetative cells of Anabaena 7120 were assayed for content of cytochrome f, cytochrome b-563, cytochrome b-559(HP), cytochrome b-559(LP), and cytochrome aa(3) by use of reduced-minus-oxidized difference spectra. The level of cytochrome aa(3) in heterocyst membranes was 4 to 100 times higher than that in vegetative cells of Anabaena 7120 or other species o...
