Carbohydrate-Binding Module Family 91

Activities in FamilyBinding to xylans (birchwood and oat spelt)
Mechanism
NoteCreated after Ito et al. 2022 [PMID=36312872] who demonstrated the xylan binding activity in the PxXyl43A protein (Paenibacillus xylaniclasticus TW1). This family also include the binding module of Fibrobacter succinogenes S85 protein FSUAXH1 described by Yoshida et al., 2010 [PMID: 20709893].
