comments
Although this enzyme is classified into hydrolases, it does not catalyzes ordinary "hydrolysis" reaction.
According to the literature [7] & [12], this enzyme catalyzes the following reactions.
(A) Isomerization (open ring), or Elimination of hydroxyl group accompanied by double-bond formation
(B) Isomerization (change in the position of double-bond), to form Schiff-base (adlimine),
(C) Schiff-base dehydration,
(D) Isomerization (close ring), or addition to double-bond.
