Comments
This enzyme is homologous to the counterpart enzymes (see S00305 and S00547 in EzCatDB).
This enzyme from archaean species (PDB; 1nks) seems to be distinct from others, and catalytic residues are not so conserved (see [32]).
The literature [12], [14], [21], [23], [24] & [27] reported that conformational change occurs upon substrate binding and during catalysis.
The transfer reaction of the gamma-phosphoryl group of ATP occurs by an in-line mechanism involving a tentacovalent-transition-state with the nucleophilic acceptor group, the oxygen atom of the phosphate group of AMP, and the leaving group, the beta-phosphate of ATP in the two apical positions (see [19]). The paper [26] suggested that the in-line phosphoryl transfer is associative (SN2-like).
The transferred phosphoryl group is stabilized by conserved residues, Lys14, and Arg139. The acceptor phosphoryl group is stabilized by Arg54 and His93.
The role of cofactor, magnesium ion, which is bound to Asp91, is discussed in the papers [17] & [31], as follows:
(1) This ion shield the negative charge of the transferred group, the gamma-phosphate of ATP from the attacking nucleophile, the acceptor oxygen atom of the alpha-phosphate of AMP, by its interaction with the gamma-phosphate.
(2) This ion enhances the cleavage of the P(gamma)-O bond by electrophilic effects.
(3) This ion orients the phosphate chain in proper positions.
