title: Total synthesis of horse heart cytochrome C.
abstract: A strategy based on complexation-assisted condensation of large synthetic protein fragments and mitochondria-mediated stereospecific heme insertion has been utilized to assemble a functional molecule corresponding to native horse heart holocytochrome c. This original approach offers the unique opportunity of selective modifications both in the C-terminal and in the N-terminal regions of the apoprotein and may represent an useful alternative to site-directed mutagenesis, particularly when D-amino acids, chemically and/or isotopically modified or other unnatural amino acids have to be introduced in this important molecule. The present result is an example of how solid phase peptide synthesis of large protein fragments in conjunction with the availability of a specific recognition process may extend the potentiality of the chemical approach to the synthesis of an entire protein.
