PH 2.5 ACID PHOSPHATASE FROM ASPERGILLUS NIGER


Overview

The crystal structure of Aspergillus niger pH 2.5 acid phosphatase (EC 3.1.3.2) has been determined at 2.4 A resolution. In the crystal, two dimers form a tetramer in which the active sites are easily accessible to substrates. The main contacts in the dimer come from the N termini, each lying on the surface of the neighbouring molecule. The monomer consists of two domains, with the active site located at their interface. The active site has a highly conserved catalytic center and a charge distribution, which explains the highly acidic pH optimum and the broad substrate specificity of the enzyme.
