摘要:
The invention relates a novel hybrid carbonic anhydrase catalyst with the potential to contribute significantly to meeting targeted reductions in greenhouse gas emissions. In a preferred embodiment of the present invention at least a portion of a cellulose binding domain (CBD) of a protein is fused to another protein, carbonic anhydrase, (CA) to create a new multifunctional protein which can bind tightly to cellulose while maintaining its native catalytic ability to process CO2. The resulting CA-CBD hybrid polypeptide can be immobilized to a cellulose support and used to cost-effectively capture CO2 from gas streams and other CO2-rich environs.

In a preferred embodiment of the present invention at least a portion of a cellulose binding domain (CBD) of a protein is fused to another protein, carbonic anhydrase, (CA) to create a new multi-functional protein which can bind tightly to cellulose while maintaining its native catalytic ability to process CO2. The resulting CA-CBD hybrid polypeptide can be immobilized to a cellulose support and used to cost-effectively capture CO2 from gas streams and other CO2-rich environs.
