Comments
This enzyme is composed of the N-terminal Pleckstrin homology (PH) domain, two EF-hand domains, Catalytic domain, and the C-terminal C2 domain.
The PH domain (PDB;1mai) seems to be important for membrane association (see [5] & [6]).
Although literature [9] & [22] mentioned that calcium ion might activate the 2-hydroxyl group for nucleophilic attack on phosphoryl group, by lowering its pKa, it is against other paper (literature of [6] for BamHI, S00384 in EzCatDB).. According to the literature [12], the ion may play a dual role, (1) stablization of the negative charge on the deprotonated 2-hydroxyl group, and (2) stabilization of the transition state.
Based on the literature [9], [12], [16] & [22], the catalytic reaction proceeds as follows:
(1) Glu341, which is bound to the calcium ion, acts as a general base to deprotonate and activate the 2-hydroxyl group of substrate, 1-Phosphatidyl-D-myo-inositol 4,5-bisphosphate (IP2) (see [16]). This activation is assisted by the calcium ion, which stabilizes the negative charge on the 2-hydroxyl group, and His311, Asn312 & Glu390, which stabilize the negative charge on the phosphate group (see [12]).
(2) The activated 2-hydroxyl group makes a nucleophilic attack on phosphodiester, to form an intermediate, cyclic IP3.
(3) His356 acts as a general acid to protonate the leaving diacylglycerole (DAG).
(4) His356, now, acts as a general base to deprotonate a water molecule.
(5) The activated water makes an attack on the phosphate group of the intermediate. Here, the leaving 2-hydroxyl group is stabilized by the calcium ion, and probably protonated by a general acid, Glu341. This hydrolysis might be facilitated by the conformational strain of the intermediate (see [12]).
