Carbohydrate-Binding Module Family 22

Activities in FamilyA xylan binding function has been demonstrated in several cases and affinity with mixed β-1,3/β-1,4-glucans in one. In several cases a thermostabilizing effect has also been seen.
3D Structure Statusβ-sandwich
NoteFormerly known as X6 modules or thermostabilizing domains
