The BACON (Bacteroidetes-Associated Carbohydrate-binding Often N-terminal) domain is an all-beta domain found in diverse architectures, principally in combination with carbohydrate-active enzymes and proteases. These architectures suggest a carbohydrate-binding function which is also supported by the nature of BACON's few conserved amino-acids. The phyletic distribution of BACON and other data tentatively suggest that it may frequently function to bind mucin [1]. Further work with the characterised structure of a member of glycoside hydrolase family 5 enzyme, PDB:3ZMR, has found no evidence for carbohydrate-binding for this domain [2].	Domain
