Temperaturstabil ss-pyranosidase

摘要

The invention relates to temperature-stable polypeptides with beta-pyranosidase activity. The polypeptide substrates include beta-glucopyranosides und beta-xylopyranosides. Said polypeptides can be expressed alone or as fusion proteins for example in yeast or bacteria and subsequently purified. The polypeptides according to said invention can be used alone or in a mixture with other enzymes for the degradation of plant raw materials, among others for the enzymatic degradation of biomass containing lignocellulose, in particular hemicellulose and the hemicellulose component xylan. Said enzymes are suitable for use in textile processing, as an additive of detergents, or in the food or feed industry.
