[A tryptic heme peptide of cytochrome c from Candida valida]

Method for direct isolation of heme peptide from enriched yeast biomass have been developed. This method makes it possible to eliminate the process of cytochrome c purification. Amino acid sequence for the Candida valida heme peptide is proposed. Exact molecular masses for both cytochrome c and its heme peptide are determined by mass-spectrometry.
