comments
This enzyme contains two binding sites for ADP-Mg2+; one is the active site between the two domains, and the other is effector site in the smaller subunit. Moreover, this enzyme has two conformational states, R- and T-states, by allosteric behavior (see [9]).
According to the literature [7], [10] & [11], the reaction proceeds as follows:
(1) Asp127 acts as a general base, whose pKa seems to be modulated by Asp129, to deprotonate the acceptor group, 1-OH of Fructose 6-phosphate (F6P). Asp129 is also involved indirectly in binding of the cofactor magnesium ion, through water molecules.
(2) The activated acceptor group makes a nucleophilic attack on the gamma-phosphate of ATP.
(3) The pentacovalent phosphoryl group is stabilized by Arg171, Arg72, Thr125 and mainchain amide of Gly11, along with the magnesium ion bound to Asp103. The magnesium ion bridges gamma- and beta-phosphate groups.
