WebDec 1, 2004 · Oxygenic photosynthesis is the principal producer of both oxygen and organic matter on earth. The primary step in this process — the conversion of sunlight into chemical energy — is driven by ... WebCytochrome c, associated with electron transport chain and inner mitochondrial membrane, can be spectrophotometrically distinguished from myoglobin by its absorption peaks at 521 and 550 nm ( Table 1 ). Relative to the myoglobin content, cytochrome c is found at lower levels in red meats than in poultry.

WebA thiosulfate-induced cytochrome c has been purified from the photosynthetic alpha-proteobacterium Rhodovulum sulfidophilum. This cytochrome c(551) is a heterodimer of a diheme 30-kDa SoxA subunit and a monoheme 15-kDa SoxX subunit. The cytochrome c(551) structural genes are part of an 11-gene sox locus. WebMay 23, 1991 · A low-potential cytochrome c from Rb. sphaeroides, which has two hemes at opposite ends of a 16 kDa protein, was apparently not doubled [16]. Pseu- domonas stutzerii cytochrome c-552 is a 26 kDa diheme protein [16,18], which shows no evidence for gene dou- bling and there is no obvious similarity to the Rb. sphaeroides cytochrome.
