Comments
This enzyme is composed of the N-terminal 5'-3' exonuclease (E.C. 3.1.11.3) domains, 3'-5' exonuclease (E.C. 3.1.11.1) domain, and the C-terminal DNA polymerase (E.C. 2.7.7.7) domains. The DNA polymerase belongs to the type-A family.
The structure and mechanism of 5'-3' exonuclease have not been elucidated yet.
According to the literature [6] & [12], the mechanisms of two active sites are as follows:
(A) Transfer of phosphoryl group from NTP to DNA (This reaction is the same as that of M00175 in EzCatDB.):
(A1) Divalent metal-1, which is bound to Asp882 and Glu883, interacts with acceptor, 3'-OH of DNA and activates it by lowering its pKa.
(A2) The acceptor, 3'-hydroxyl group, makes a nucleophilic attack on the transferred alpha-phosphoryl group of dNTP.
(A3) Divalent metal-1 and metal-2 stabilize the transition state by interacting with the transferred group, whereas the leaving groups, beta- and gamma-phosphate groups, are stabilized by divalent metal-2 along with mainchain amide of Gln708 and Ile 709, sidechain of Arg682, His734, Arg754 and Lys758.
(B) Hydrolysis of phosphoric ester of DNA:
(B1) Divalent metal-A, which is bound to Asp355, Glu357 & Asp501, activates a water moclecule by lowering its pKa. The position of this water is oriented by Glu357 & Tyr497.
(B2) The activated water makes a nucleophilic attack on the phosphoryl atom.
(B3) Divalent metal-A and metal-B stabilize the transition state by interacting with the transferred group, whereas the negative charge on the leaving group, 3'-oxyanion, is stabilized by divalent metal-B.
