Abstract:
:Cytochrome c biogenesis describes the posttranslational pathway for the conversion of pre-apocytochrome c into the mature holocytochrome c. It involves an unknown number of consecutive biochemical steps, including translocation of the precursor polypeptide and haem into the periplasm and the covalent linkage between these two molecules. Genetic and molecular analysis of several bacterial mutants suggest that at least eight genes contribute to this process. In this review we summarize the present knowledge of the cytochrome c maturation pathway in bacteria and propose a model in which certain genes and their products are attributed to specific functions.
