Uncharacterized conserved protein, DUF1680 family [Function unknown].

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.

AGE domain; N-acyl-D-glucosamine 2-epimerase domain; Responsible for intermediate epimerization during biosynthesis of N-acetylneuraminic acid. Catalytic mechanism is believed to be via nucleotide elimination and readdition and is ATP modulated. AGE is structurally and mechanistically distinct from the other four types of epimerases. The AGE domain monomer is composed of an alpha(6)/alpha(6)-barrel, the structure of which is also found in glucoamylase and cellulase. The active form is a homodimer. The alignment also contains subtype III mannose 6-phosphate isomerases.
