Carbohydrate-Binding Module Family 43

Activities in Family	Modules of approx. 90-100 residues found at the C-terminus of GH17 or GH72 enzymatic modules and also sometimes isolated. CBM43 modules sometimes carry a C-terminal membrane anchor. The β-1,3-glucan binding function has been demonstrated with the olive pollen protein Ole e 10.
