Determination of the structure of an endoglucanase from Aspergillus niger and its mode of inhibition by palladium chloride.

The fungus Aspergillus niger is a main source of industrial cellulase. beta-1,4-Endoglucanase is the major component of cellulase from A. niger.

Structure of an endoglucanase from termite, Nasutitermes takasagoensis.

Contrary to conventional wisdom, it has been shown recently that termites do not necessarily depend on symbiotic bacteria to process cellulose. They secrete their own cellulases, mainly endo-beta-1,4-glucanase and beta-1,4-glucosidase. Here, the first structure of an endogenous endoglucanase from the higher termite Nasutitermes takasagoensis (NtEgl) is reported at 1.
