comments
Although this enzyme classified into hydrolase (E.C. 3.-.-.-), it does not catalyzes hydrolysis. According to the literature [18], [19], [20], [23] & [25], this enzyme catalyzes the following reactions succesively, although the detailed mechanism has not been elucidated.
(I) glycosylase reaction to form Schiff-base intermediate.
(A) Transfer of deoxyribose group from pyrimidine dimer to the N-terminal alpha-amino group.
(B) Eliminative double-bond formation; Ring opening of deoxyribose, forming Schiff-base intermediate.
(II) AP lyase reaction.
(C) Isomerization; Shift of double-bond from Schiff-base to adjacent bond.
(D) Eliminative double-bond formation; beta-elimination of 3'-phosphate from the opened deoxyribose group.
(E) Exchange of double-bonded atoms; Schiff-base deformation (hydration)
####
The N-terminal alpha-amino group of Thr2 forms Schiff-base with C1' atom of the deoxyribose. Glu23 seems to be required for both reactions, (I) & (II).
