Biochemical and structural characterization of Penicillium purpurogenum α-D galactosidase: Binding of galactose to an alternative pocket may explain enzyme inhibition.

Abstract excerpt

The fungus Penicillium purpurogenum degrades plant cell walls by the action of cellulolytic, xylanolytic and pectinolytic enzymes. The α-D-galactosidase is one of the enzymes which may act on pectin degradation. This enzyme has several biotechnological and medical applications. The aim of this work was to better understand the molecular mechanism of α-D-galactosidase from P. purpurogenum (GALP1). For this...
