title: Expression, purification, and characterization of exo-beta-D-glucosaminidase of Aspergillus sp. CJ22-326 from Escherichia coli.
abstract: An exo-beta-D-glucosaminidase gene was cloned from Aspergillus sp. CJ22-326 and expressed in Escherichia coli. The purified protein showed an exo-chitosanase activity in a viscosimetric assay and TLC analysis. This is the first report on cloning of a gene encoding an Aspergillus sp. exo-beta-D-glucosaminidase.
