pfam13004: BACON (This model is not part of the current CDD release)
Putative binding domain, N-terminal
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. 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.
