Fig. 2. Optimization of the reaction conditions used in the biomimetic transamination reaction.

a Screening of oxidants Ox1-Ox8 used for the transamination reaction with model peptide 1; b LC trace obtained for the transamination reaction using Ox1 in yellow or Ox2 in blue; c pH Optimization of the transamination reaction using Ox1 in yellow or Ox2 in blue (the rate of conversion was calculated by integrating the related peaks of the LC trace measured at 280 nm. Centers represent means, error bars represent standard deviation, n = 3 independent replicates).
