KIDNEY BEAN PURPLE ACID PHOSPHATASE
Overview
Purple acid phosphatase is a widely distributed non-specific, phosphomonoesterase. X-ray structures of the dimeric 111-kDa, Fe(III)-Zn(II) kidney bean purple acid phosphatase (kbPAP) complexed with, phosphate, the product of the reaction, and with tungstate, a strong, inhibitor of the phosphatase activity, were determined at 2.7 and 3.0, angstroms resolution, respectively. Furthermore the resolution of the, unligated enzyme, recently solved at 2.9 angstroms could be extended to, 2.65 angstroms with completely new data. The binding of both oxoanions is, not accompanied by larger conformational changes in the enzyme structure., Small movements with a maximal coordinate shift of 1 angstroms are only, observed for the active site residues His295 and His296. In the inhibitor, complex as well ... [(full description)]
