PF22676 | Alpha-galactosidase, N-terminal (GalA_N) | Alpha-galactosidase, N-terminal | 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-te ... | Domain | |
