Glycosyl hydrolase catalytic core. This family is probably a glycosyl hydrolase, and is conserved in fungi and some Proteobacteria. The pombe member is annotated as being from IPR013781.

Por secretion system C-terminal sorting domain. Species that include Porphyromonas gingivalis, Fibrobacter succinogenes, Flavobacterium johnsoniae, Cytophaga hutchinsonii, Gramella forsetii, Prevotella intermedia, and Salinibacter ruber average twenty or more copies of a C-terminal domain, represented by this model, associated with sorting to the outer membrane and covalent modification.

Secretion system C-terminal sorting domain. Species that include Porphyromonas gingivalis, Fibrobacter succinogenes, Flavobacterium johnsoniae, Cytophaga hutchinsonii, Gramella forsetii, Prevotella intermedia, and Salinibacter ruber have on average twenty or more copies of this C-terminal domain, associated with sorting to the outer membrane and covalent modification. This domain targets proteins to type IX secretion systems and is secreted then cleaved off by a C-terminal signal peptidease. Based on similarity to other families it is likely that this domain adopts an immunoglobulin like fold.

Carbohydrate Binding Module 6 (CBM6); appended mainly to glycoside hydrolase (GH) family 16 alpha- and beta agarases. This family includes carbohydrate binding module 6 (CBM6) domains that are appended mainly to glycoside hydrolase (GH) family 16 agarases. These CBM6s are non-catalytic carbohydrate binding domains that facilitate the activity of alpha- and beta-agarase catalytic modules which are involved in the hydrolysis of 1,4-beta-D-galactosidic linkages. These CBM6s bind specifically to the non-reducing end of agarose chains, recognizing only the first repeat of the disaccharide, and directing the appended catalytic modules to areas of the plant cell wall attacked by beta-agarases. CBM6 is an unusual CBM as it represents a chimera of two distinct binding sites with different modes of binding: binding site I within the loop regions and binding site II on the concave face of the beta-sandwich fold. This family includes three tandem CBM6s from the Saccharophagus degradans agarase Aga86E, and three tandem CBM6s from Vibrio sp. strain PO-303 AgaA; in both these proteins these are appended to a GH16 domain. Vibrio AgaA also contains a Big-2-like protein-protein interaction domain. This family also includes two tandem CBM6s from an endo-type beta-agarase from a deep-sea Microbulbifer-like isolate, which are appended to a GH16 domain, and two of three CBM6s of Alteromonas agarilytica AgaA alpha-agarase, which are appended to a GH96 domain.
