Abstract

Crystals of a new inhibitor present in rye seeds active against alpha-amylases from crop pests Acanthoscelides obtectus and Zabrotes subfasciatus have been obtained. A native dataset was collected at 2.21 Å resolution with 99.3 % completeness at CPr beamline at LNLS. The crystals belong to the trigonal system, space group P3121 with a = b = 78.21 Å, and c = 59.61 Å. The crystal calculated solvent content is compatible with one dimer per asymmetric unit.
