The ability of each AA3_2 to use phenoxy radical as an electron acceptor. Reactions with a TaGdhA, b KiOdhA, and c ApGoxA were followed at 320 nm for the depletion of ferulic acid. d PsAaoA was followed at 350 nm for the formation of ferulic acid dimer. Reaction with laccase to KiOdhA in a ratio of 1–2 was also displayed in d for comparison. The enzymes were dosed according to the specific activity of laccase and AA3_2s. For the specific activity of TaGdhA and KiOdhA, BQ was used, and for the specific activity of ApGoxA and PsAaoA, oxygen was used
