Different Pool Sizes of the Precursor Polypeptides of Cytochrome Oxidase from Neurospora crassa

Pulse‐labelling experiments with growing Neurospora crassa revealed that the polypeptides composing the protein moiety of a cytochrome oxidase preparation are derived from at least four independent pools of precursor polypeptides. The pool sizes range from 2% to 25% of the amount of the correspondin...

More Information
Summary:Pulse‐labelling experiments with growing Neurospora crassa revealed that the polypeptides composing the protein moiety of a cytochrome oxidase preparation are derived from at least four independent pools of precursor polypeptides. The pool sizes range from 2% to 25% of the amount of the corresponding polypeptide present in cytochrome oxidase. The smallest pool is assigned to a polypeptide of mitochondrial origin. Serial pools were found for one of the polypeptides.
