Cytochrome c heme lyase
WebOct 18, 2005 · Type c cytochromes are hemoproteins that play an essential role in respiratory and photosynthetic electron transport. In prokaryotes and eukaryote organelles, they function on the so-called p-side of the energy-transducing membranes.They are characterized by the covalent ligation of two vinyl groups of the prosthetic heme to the … WebThus, covalent heme attachment is a required step for import of cytochrome c into mitochondria. Heme attachment, however, can occur in the absence of mitochondrial import since we have detected CYC3-encoded heme lyase activity in solubilized yeast extracts and in an Escherichia coli expression system. These results suggest that protein folding ...
