Fig. 3From: A Penicillium chrysogenum-based expression system for the production of small, cysteine-rich antifungal proteins for structural and functional analysesESI-MS data showing the isotopic average molecular mass (m/z) of a PAF[Pc], b PAFF31N, c PAFY48Q, d NFAP[Pc] and e PAF[Pd]. The last four amino acid residues of the pro sequence (underlined), the first four of the predicted mature proteins, and the experimentally determined N-terminal cleavage sites (arrowheads) are shown on each major MS peakBack to article page
