WebSep 6, 2011 · In animal, fungal and protozoan mitochondria cytochrome c production relies on the protein holocytochrome c synthase, HCCS (also called heme lyase). HCCS has a well documented role in the import of the apocytochrome into the mitochondrion [ 4 , 5 ] , but its role in the covalent attachment reaction of heme to the protein is poorly understood. WebMay 29, 2024 · In one class, an N-terminal P450 heme domain is fused to a C-terminal NADPH:cytochrome P450 reductase (CPR) that contains a flavin mononucleotide (FMN)-binding flavodoxin and a FAD/NADPH …

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 ... sublime events stirling
