Abstract
Compositions and methods are provided for reversibly binding chitin binding domain (CBD) to a chitin or equivalent substrate under non denaturing conditions. CBD is modified preferably by a mutation to achieve this change in properties. In one embodiment, an aromatic amino acid residue located in the binding cleft of the CBD was altered resulting in reversible binding affinity for substrate in select conditions. Creating a modified CBD with an altered binding affinity for substrate provides new uses for CBD not previously possible with unmodified CBD which binds irreversibly to chitin.
