Comments
This enzyme belongs to the Aspartate aminotransferase (AAT) subclass of type-I PLP-dependent enzyme superfamily (Aspartate aminotransferase superfamily; AAT).
This enzyme catalyzes transamination, which is composed of the following reactions:
(A) Formation of external aldimine (with amine group of L-Aspartate),
(B) Isomerization (change in the position of double-bond), forming a ketimine intermediate.
(C) Schiff-base deforming by hydration, releasing the first product, oxaloacetate, and PMP.
(D) Schiff-base forming of PMP with carbonyl group of the second substrate, 2-oxoglutarate, leading again to a ketimine intermediate.
(E) Isomerization (change in the position of double-bond).
(F) Formation of internal aldimine, leading to the elimination of the product from PLP.
These reactions proceed in the following way:
(A) Formation of external aldimine (with amine group of L-Aspartate) (see [11], [13], [18] & [46])
(A1) Tyr225 interacts with O3' atom of PLP, when the PLP-aldimine is protonated, modulating and keeping the O3' of PLP negatively charged (see [13]).
(A2) The negatively charged O3 atom of PLP modulates the pKa of the alpha-amino group of substrate, L-aspartate, and also the pKa of the internal aldimine with Lys258. Here, according to the literature [46], [59] & [61], the imine-pyridine torsion (or strain) of PLP-Schiff base lowers pKa of the internal aldimine, without lowering the external aldimine. In any case, the difference in the pKa values facilitates the proton transfer from the alpha-amino group of L-aspartate to the NZ nitrogen of Lys258.
(A3) The deprotonated amine group of L-aspartate makes a nucleophilic attack on the C4' carbon of PLP, forming a transient geminal diamine intermediate.
(A4) There must be a general base, which deprotonates the amine group of the previously L-aspartate substrate, so that the lone pair of the amine group can attack on the C4' atom to form a double-bond, and to release the amine of the catalytic residue, Lys258. Considering the active-site structure, Tyr70' (from the adjacent chain) may play the role as the general base, although the literature has not mentioned it (except for the literature [11]). (The released Lys258 must be deprotonated, so that it can act as a general base at the next stage.)
(A5) The reaction produces the external aldimine with L-aspartate.
(B) Isomerization (change in the position of double-bond), forming a ketimine intermediate (see [17], [18], [20], [21], [22] & [24]).
(B1) Asp222 interacts with the N1 atom of PLP, modulating and enhancing the activity of the PLP cofactor as an electron sink, which facilitates the abstraction of alpha-proton from the aspartate covalently bound to the PLP (see [17] & [24]). At the same time, Tyr225 also interacts with the O3' atom of the PLP, modulating the activity of the PLP (see [13]).
(B2) Lys258 acts as a general base to deprotonate the alpha-proton of the amino acid substrate, forming a quinonoid intermediate.
(B3) Lys258 acts as a general acid to protonate the C4' atom of the PLP, leading to the formation of a ketimine intermediate.
(C) Schiff-base deforming by hydration, releasing the first product, oxaloacetate, and PMP (see [18] & [26]).
(C1) Lys258 acts as a general base to activate a water (at the si-face side of cofactor).
(C2) The activated water molecule makes a nucleophilic attack on the alpha-carbon atom of the substrate (from the si-face side), forming a carbinolamine intermediate.
(C3) Lys258 may act as a general acid to protonate the N4' atom of the PLP. Tyr225 may modulate the activity of Lys258. (Tyr225 is hydrogen-bonded to the O3 atom of the PLP).
(C4) The lone pair of the hydroxyl oxygen makes a nucleophilic attack on the C4' atom, whereas Lys258 acts as a general base to deprotonate the hydroxyl group, releasing the first product, oxaloacetate and the PMP.
(D) Schiff-base forming of PMP with carbonyl group of the second substrate (see [18] & [26])
(D1) The second substrate, 2-oxoglutarate, is bound to the active site, with the carbonyl oxygen hydrogen-bonded by Lys258.
(D2) The amine group (or the N4' atom) of PMP is unprotonated and makes a nucleophilic attack on the carbonyl carbon of the substrate, whereas Lys258 acts as a general acid to protonate the carbonyl oxygen, forming a carbinolamine intermediate.
(D3) Lys258 acts as a general base to deprotonate the N4 amine group. Tyr225 may modulate the activity of Lys258. (Tyr225 is hydrogen-bonded to the O3 atom of the PLP).
(D4) The lone pair of the N4' nitrogen atom makes a nucleophilic attack on the carbon atom, whereas Lys258 acts as a general acid to the hydroxyl group of the carbinolamine intermediate, leading to the cleavage between the carbon and the N4' atom, and to the release of a water moleucle. This reaction gives a ketimine intermediate again.
(E) Isomerization (change in the position of double-bond): (Inverse reaction of (B))
(E1) Asp222 modulates and enhances the activity of the PLP cofactor as an electron sink, which facilitates the abstraction of alpha-proton from the C4' atom of the PLP.
(E2) Lys258 acts as a general base to deprotonate the C4' atom of the PLP, leading to the formation of a quinonoid intermediate.
(E3) Lys258 acts as a general acid to protonate the alpha-proton of the amino acid substrate, forming an external aldimine. (As a result, Lys258 must be deprotonated, so that it can act as a general base at the next stage.)
(F) Formation of internal aldimine, leading to the elimination of the product from PLP: (Inverse reaction of (A))
(F1) Tyr225 interacts with O3' atom of PLP, when the PLP-aldimine is protonated, modulating and keeping the O3' of PLP negatively charged (see [13]).
(F2) The deprotonated amine group of Lys258 makes a nucleophilic attack on the C4' carbon of the PLP of the external aldimine, forming a transient geminal diamine intermediate. On the other hand, there must be a general acid, which protonates the N4' nitrogen atom of the external aldimine or the geminal diamine. Considering the active-site structure, Tyr70' (from the adjacent chain) may play the role as the general acid, although the literature has not mentioned it (except for the literature [11]).
(F3) The lone pair of the amine nitrogen of Lys258 can attack on the C4' atom to form a double-bond, and to release the amine of the second product, L-glutamate.
(F4) The negatively charged O3 atom of PLP modulates the pKa of the alpha-amino group of product, L-glutamate, and also the pKa of the internal aldimine with Lys258. In any case, the difference in the pKa values facilitates the proton transfer from the NZ nitrogen of Lys258 to the alpha-amine group of L-glutarate.
The pKas of the related groups are as follows (see [46]):
Unliganded internal aldimine; 6.8
Internal aldimine complexed with substrate/product; 8.1
External aldimine; 10.2
