Resumo

Endoglucanases are important enzymes that are involved in the modification and degradation of cellulose. Filamentous fungi such as Aspergillus terreus are effective biomass degraders in nature owing to their capacity to produce an enzymatic arsenal of glycoside hydrolases, including endoglucanase from glycoside hydrolase family 12 (GH12). The A. terreus GH12 endoglucanase was cloned and overexpressed in A. nidulans, purified and crystallized. A single crystal was obtained from a solution consisting of 2 M ammonium sulfate, 5%(v/v) 2-propanol. X-ray diffraction data were collected to a resolution of 1.85 angstrom using synchrotron radiation and a preliminary molecular-replacement solution was obtained in the trigonal space group P3(2)21. The unit-cell parameters were a = b = 103.24, c = 48.96 angstrom. (AU)
