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].

Concanavalin A-like lectin/glucanases superfamily. This domain belongs to the Concanavalin A-like lectin/glucanases superfamily.

Cadherin-like beta sandwich domain. This domain is found in several bacterial, metazoan and chlorophyte algal proteins. A profile-profile comparison recovered the cadherin domain and a comparison of the predicted structure of this domain with the crystal structure of the cadherin showed a congruent seven stranded secondary structure. The domain is widespread in bacteria and seen in the firmicutes, actinobacteria, certain proteobacteria, bacteroides and chlamydiae with an expansion in Clostridium. In contrast, it is limited in its distribution in eukaryotes suggesting that it was derived through lateral transfer from bacteria. In prokaryotes, this domain is widely fused to other domains such as FNIII (Fibronectin Type III), TIG, SLH (S-layer homology), discoidin, cell-wall-binding repeat domain and alpha-amylase-like glycohydrolases. These associations are suggestive of a carbohydrate-binding function for this cadherin-like domain. In animal proteins it is associated with an ATP-grasp domain.
