A new type of membrane-bound cytochrome c was found in a marine purple photosynthetic bacterium, Rhodovulum sulfidophilum. This cytochrome c was significantly accumulated in cells growing under anaerobic photosynthetic conditions and showed an apparent molecular mass of approximately 100 kDa when purified and analyzed by SDS-PAGE. The midpoint potential of this cytochrome c was 369 mV. Flash-in...

The mouse testis contains two isotypes of cytochrome c, which differ in 14 of 104 amino acids: cytochrome cs is present in all somatic tissues and cytochrome cT is testis specific. The regulation of cytochrome cS and cytochrome cT gene expression during spermatogenesis was examined by Northern blot analysis using specific cDNA probes. Total RNA was isolated from adult tissues, enriched germinal...

The reaction of the electrostatic cytochrome c-cytochrome oxidase complex with oxygen is measured by transient absorption spectroscopy. The oxygen reaction is initiated by photolytic removal of CO from cytochrome oxidase, using a flash-pumped dye laser. The subsequent reaction of the cytochrome c-cytochrome oxidase complex with oxygen is reported at 550, 605, 744, and 830 nm at different cytoch...

We purified membrane-bound cytochrome c-550 [cytochrome c-550(m)] to an electrophoretically homogeneous state from Nitrobacter winogradskyi. The cytochrome showed peaks at 409 and 525 nm in the oxidized form and peaks at 416, 521, and 550 nm in the reduced form. The molecular weight of the cytochrome was estimated to be 18,400 on the basis of protein and heme c contents and 18,600 by gel filtra...
