Cellulase (glycosyl hydrolase family 5).

Bacteroidetes-Associated Carbohydrate-binding (putative) Often N-terminal (BACON) domain. The BACON domain is found in diverse domain architectures and accociated with a wide variety of domains, including carbohydrate-active enzymes and proteases. It was named for its suggested function of carbohydrate binding; the latter was inferred from domain architectures, sequence conservation, and phyletic distribution. However, recent experimental data suggest that its primary function in Bacteroides ovatus endo-xyloglucanase BoGH5A is to distance the catalytic module from the cell surface and confer additional mobility to the catalytic domain for attack of the polysaccharide. No evidence for a direct role in carbohydrate binding could be found in that case. The large majority of BACON domains are found in Bacteroidetes.

Aryl-phospho-beta-D-glucosidase BglC, GH1 family [Carbohydrate transport and metabolism].

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 characterized structure of a member of glycoside hydrolase family 5 enzyme, Structure 3ZMR, has found no evidence for carbohydrate-binding for this domain.

Viral BACON domain. This family represents a distinct class of BACON domains found in crAss-like phages, the most common viral family in the human gut, in which they are found in tail fiber genes. This suggests they may play a role in phage-host interactions.
