The domain is found in both bacteria and eukaryotes, including Bacteroidota, Bacillota, Pseudomonadota and fungi. It occurs downstream of the GH31 catalytic TIM barrel domain (Pfam:PF01055) and the proximal C-terminal domain (Pfam:PF21365). GH31 enzymes containing this domain include alpha-xylosidases involved in xyloglucan saccharification [1], alpha-glucosidases, and glucosidase II alpha subunits. In Saccharomyces cerevisiae, the glucosidase II alpha subunit ROT2 (Swiss:P38138) cleaves the two innermost alpha-1,3-linked glucose residues from the oligosaccharide precursor of immature glycoproteins in the endoplasmic reticulum (EC:3.2.1.207) [3]. Structural studies of the Chaetomium thermophilum glucosidase II alpha subunit show that the distal C-terminal domain stabilises the catalytic beta8-alpha8 barrel domain [2].
