Characterization of an Antihypertensive Angiotensin I-Converting Enzyme Inhibitory Peptide from the Edible Mushroom Hypsizygus marmoreus

Figure 2

Amino acid sequence of the purified oligopeptide (P-1) from H. marmoreus by LC-MS/MS. MS/MS experiments were performed on a LCQ-Deca ESI ion trap mass spectrometer (Thermo Finnigan Co., USA). For protein identification, the MS/MS spectra were searched using SEQUEST (ver 3.3) software. (P-1, TTENVLFG).
