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. fnf mobile dave and bambi
Cytochrome b6f complex - Wikipedia
The heme group is a highly conjugated ring system (which allows its electrons to be very mobile) surrounding an iron ion. The iron in cytochromes usually exists in a ferrous (Fe ) and a ferric (Fe ) state with a ferroxo (Fe ) state found in catalytic intermediates. Cytochromes are, thus, capable of performing electron transfer reactions and catalysis by reduction or oxidation of their heme iron. The cellular location of cytochromes depends on their function. They can be found as globular proteins http://hyperphysics.phy-astr.gsu.edu/hbase/Organic/Cytochrome.html 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. fnf mobile gameplay
