Representative Chromatogram of ELA-32(1-21) (A) and ELA-11 (B) generated from ELA-32. The metabolites were produced from the hydrolysis of mature ELA-32 between Arg21 and Cys22, but the hydrolytic enzyme is unknown. ELA-32(1-21), retention time 38.30 min; ELA-11, retention time 43.76 min, was only present in the oxidised form (methionine oxidation). The red line indicates the cleavage point.
