Alpha-L-arabinofuranosidases: biochemistry, molecular biology and application in biotechnology.
Interest in the alpha-L-arabinofuranosidases has increased in recent years because of their application in the conversion of various hemicellulosic substrates to fermentable sugars for subsequent production of fuel alcohol. Xylanases, in conjunction with alpha-L-arabinofuranosidases and other accessory enzymes, act synergistically to degrade xylan to component sugars. The induction of alpha-L-arabinofuranosidase production, physico-chemical characteristics, substrate specificity, and molecular biology of the enzyme are described. The current state of research and development of the arabinofuranosidases and their role in biotechnology are presented.
