Normalized MS peak areas in time of reaction products formed upon incubation of GBG with laccase alone (A), laccase/HBT (B), and laccase/ABTS (C). Areas were obtained from extracted ion chromatograms: GBG (m/z 343) (black dot), GBG dimer (m/z 637) (red dot), GBG trimer (m/z 955) (blue dot), GBG-HBT CP (m/z 452) (grey dot), GBG-HBT CPox (m/z 450) (open dot, grey line), GBGox (m/z 319 and 341) (open dot, black line), GBG-ABTS CPIox (m/z 414) (green dot), GBG-ABTS CPII (m/z 588) (purple dot), GBG-ABTS CPIIox (m/z 586) (open dot, purple line) and ABTS CLP (m/z 258) (orange dot). For the abundance (Y axis), the time point with the largest peak area was set to 100%. For the other time points, the abundance was calculated as the peak area relative to the area of this largest peak. Amounts withdrawn per time point and injected to UHPLC-MS analysis were the same for all time points.
