Ligand specificities
CBM91 bind oat spelt xylan with Ka value of 2.0×10-5 M-1, and can bind birchwood xylan. But it does not bind to cellulosic substrates, carboxymethyl-cellulose, ball-milled cellulose and lichnan. So, CBM91 can recognize and bind to insoluble xylan [1].
Structural Features
- Fold: β-sandwich
- Type: Type B
Functionalities
Family Firsts
- First Identified
- CBM91 from Paenibacillus xynaniclasticus strain TW1 [1].
- First Structural Characterization
- β-D-xylosidase, a family 43 glycoside hydrolase from Clostridium acetobutylicum ATCC 824 PDB ID 1Y7B.
