Glycosyl hydrolase family 53. This domain belongs to family 53 of the glycosyl hydrolase classification. These enzymes are enzymes are endo-1,4- beta-galactanases (EC:3.2.1.89). The structure of this domain is known and has a TIM barrel fold.

Arabinogalactan endo-1,4-beta-galactosidase [Carbohydrate transport and metabolism].

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.
