Carbohydrate-Binding Module Family 32

Activities in FamilyBinding to galactose and lactose has been demonstrated for the module of Micromonospora viridifaciens sialidase (PMID: 16239725). Binding to polygalacturonic acid has been shown for a Yersinia member (PMID: 17292916). Binding to LacNAc (β-D-galactosyl-1,4-β-D-N-acetylglucosamine) has been shown for an N-acetylglucosaminidase from Clostridium perfingens (PMID: 16990278).
3D Structure Statusβ-sandwich
NoteFormerly known as X56 modules. Distantly related to CBM6 modules and to Anguilla anguilla agglutinin.
