CelB

CelB is a protein that belongs to the family of cellulose-binding domains (CBDs). It is found in various organisms, including bacteria, fungi, and plants, and plays a crucial role in the degradation and synthesis of cellulose, a major component of plant cell walls. CelB proteins are characterized by their ability to bind to cellulose, which facilitates the enzymatic hydrolysis of cellulose into glucose. This process is essential for the breakdown of plant biomass, a key step in the production of biofuels and other bioproducts.

The structure of CelB proteins typically consists of a CBD, which is responsible for cellulose binding, and a catalytic domain, which performs the enzymatic activity. The CBD is usually located at the N-terminus of the protein, while the catalytic domain is located at the C-terminus. The interaction between the CBD and cellulose is mediated by hydrogen bonds and hydrophobic interactions.

CelB proteins have been extensively studied due to their potential applications in biofuel production and other biotechnological processes. Recent research has focused on engineering CelB proteins with improved cellulose-binding affinity and catalytic activity, as well as on understanding the molecular mechanisms underlying their function. The development of CelB-based enzymes and other biotechnological tools is expected to contribute to the advancement of sustainable and environmentally friendly technologies.
