Fig. 3From: Purification and characterization of a cytochrome c with novel caspase-3 activation activity from the pathogenic fungus Rhizopus arrhizus MS spectra of the recombinant Rhizopus cyt c and MS/MS spectra of native Rhizopus cyt c collected on a MALDI TOF/TOF instrument. a MS spectra of the recombinant protein digested with trypsin. b MS/MS of precursor peptide (1166.67Â Da) from the native R. arrhizus cyt c protein digested with trypsin. Mascot online server was used to confirm the identity of both native and the recombinant proteinsBack to article page
