Beta-L-arabinofuranosidase, GH127. One member of this family, from Bidobacterium longicum, UniProtKB:E8MGH8, has been characterized as an unusual beta-L-arabinofuranosidase enzyme, EC:3.2.1.185. It rleases l-arabinose from the l-arabinofuranose (Araf)-beta1,2-Araf disaccharide and also transglycosylates 1-alkanols with retention of the anomeric configuration. Terminal beta-l-arabinofuranosyl residues have been found in arabinogalactan proteins from a mumber of different plantt species. beta-l-Arabinofuranosyl linkages with 1-4 arabinofuranosides are also found in the sugar chains of extensin and solanaceous lectins, hydroxyproline (Hyp)2-rich glycoproteins that are widely observed in plant cell wall fractions. The critical residue for catalytic activity is Glu-338, in a ET/SCAS sequence context.

Uncharacterized conserved protein, DUF1680 family [Function unknown].

Domain of unknown function. This family around 150 residues locates in the C-terminal of some uncharacterized proteins in various Bacteroides and Bacillus species. The function of this family remains unknown.

beta porphyranase A C-terminal. This is the C-terminal domain found in Bacteroides plebeius of proteins such as beta-porphyranase A (BPA), a beta-galactanase that cleaves the beta-1,4 glycosidic bond. Porphyranase degrade red seaweed glycans. This domain adopts a beta sandwich shape.
