comments
This enzyme belongs to the glycosidase family-13 (or family of alpha-amylase).
Although this enzyme binds two calcium ions on the catalytic domain, they are not involved in catalytic reaction.
According to the literature [20], [31], [34], [35], [36] & [39], the reaction proceeds as follows:
(1) Asp328 (and/or His327) modulate(s) the activity of Glu257 by raising its pKa, so that the carboxylate of Glu257 is protonated to act as a general acid.
(2) Glu257 acts as a general acid, to protonate the leaving O4 atom, leading to the formation of oxocarbonium transition-state (SN1-like reaction). This transition state is stabilized by Asp328 and His327.
(3) Asp229 acts as a nucleophile, attacking the C1 atom to form a covalent bond with it, which is an intermediate.
(4) The acceptor group, O4 hydroxyl group of the non-reducing end, approaches the active site.
(5) Glu257 acts as a general base to deprotonate the acceptor, O4 hydroxyl group.
(6) The O4 hydroxyl group makes a nucleophilic attack on the C1 atom, leading to the formation of oxocarbonium transition-state (SN1-like reaction). This transition state is stabilized by Asp328 and His327.
(7) Finally, Asp229 is releaased.
