hydroxyatrazine with an m/z of 198.13 and cyanuric acid with an m/z of 130.07 (Figure ). From the initial timepoint (0 h), BNNS-Arg@Lac group has produced a higher level of hydroxyatrazine and faster production of cyanuric acid than nlaccase group. This result implied BNNS-Arg@Lac catalyzes ATR with a higher turnover rate. In addition, the observation aligned with previous reports of enzyme inhibition by ATR and similar s-triazine derivatives in human liver microsomes. Therefore, the disparity in degradation results could also stem from the product inhibition on nlaccase by other intermediates formed during ATR degradation.
