This domain is found at the N-terminal end of Alpha-galactosidase from Thermotoga maritima (GalA), which hydrolyses the short-chain alpha-galactosaccharides raffinose, melibiose and stachyose. This GH36 enzyme is organised into three domains: an N-terminal beta -sandwich fold domain (this entry), a canonical (beta/alpha)8-fold domain housing the active site (Pfam:PF02065), and a C-terminal beta-sandwich domain with a Greek-key motif [2].
