Possible Mechanisms of Membrane Transport of Proteins: Cytochrome C Transfer Through Mitochondrial Membranes and Its Role in Cryorenewal Mechanism
Keywords:mitochondria, cytochrome C, cryorenewal, low temperatures
There is a briefly illustrated the statement about the composition of cytochrome transfer systems consisting, at least, of two molecular components. One of them is specific protein-carrier, recognising polypeptides by means of receptor function and thereby facilitating their movement through membranes. The second one is the system, providing the energy transfer to a molecule-carrier, due to that it can transfer polypeptides through mitochondrial membranes. The leading role of cytochrome C in cryorenewal mechanism is mostly stipulated by the low temperature regulation of genes, under whose control there are cytochrome C and NAD.H, participating in its transport function through an external mitochondrial membrane, as well as by the capability of low temperatures to modify the structure and function of mitochondria towards more favourable cytochrome C interaction with them.
