5.4.99.15 | additional information | the archaeal enzyme catalyzes an intramolecular transglycosylation reaction and converts the glycosidic bond at the reducing end of dextrins from alpha-1,4 (reducing end) into alpha-1,1 (non-reducing end). Maltodextrin and maltooligosaccharide are used as substrates by the enzyme but maltose, chitooligosaccharide, sucrose and beta-cyclodextrin are no substrates | Sulfurisphaera tokodaii | ? | - |
