Figure 1
Ester-hydrolysis mechanism (left) and the postulated haloperoxidase mechanism (right) (Hofmann et al., 1998  ). Both form an acyl-enzyme intermediate. In esterases, H2O attacks this intermediate to complete hydrolysis. In haloperoxidases, the acyl-enzyme intermediate comes from acetate added to the reaction mixture. Hydrogen peroxide attacks this intermediate to form a peracid. The subsequent reaction of peracid with halide form hypohalous acid; the subsequent alkyl halogenation may not be enzyme-catalyzed. |
