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.
About this Structure
1HJK is a Single protein structure of sequence from Escherichia coli with ZN, MG and SO4 as ligands. Active as Alkaline phosphatase, with EC number 3.1.3.1 Known structural/functional Sites: and . Full crystallographic information is available from OCA.
