Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in rat Cyb5b often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
- nitrite reductase
- ubiquinol-cytochrome-c reductase
- Cytochrome b5-like Heme/Steroid binding domain
- enzyme
