ALKALINE PHOSPHATASE MUTANT H331Q
Overview
Using a mutant version of E. coli alkaline phosphatase, we succeeded in trapping and determining the structure of the phospho-enzyme intermediate. The X-ray structure also revealed the catalytic water molecule, bound to one of the active site zinc ions, positioned ideally for the apical attack necessary for the hydrolysis of the intermediate.
