title: Peptide 68-88 of apocytochrome c plays a crucial role in its insertion into membrane and binding to mitochondria.
abstract: Apocytochrome c (Apocyt. c) is the precursor of cytochrome c. It is synthesized in the cytosol and posttranslationally imported into mitochondria. In order to determine the crucial sequence in apocyt. c translocation, deleted mutant and chemically synthesized peptides with different length were used. Obtained results showed that sequence 68-88 of apocyt. c plays a critical role in its insertion into membrane and binding to mitochondria.
