ABSTRACTGlycyrrhiza uralensis Fisch is a kind of commonly used herb in traditional Chinese medicine. Effective ingredients in Glycyrrhiza uralensis Fisch has anti-inflammatory and anti-virus effect. In this paper, the main physical characteristics of ?-D-xylosidase from Glycyrrhiza uralensis Fisch are studied from the perspective of bioinformatics. The composition isoelectric point and hydrophobicity etc, of the polypeptide are studied by bioinformatics tools. The results show that the molecular weight of ?-D-xylosidase in Glycyrrhiza uralensis Fisch is 31136.85, the theoretical isoelectric point is 9.56, the instability index is 29.87, the polypeptide does not exist in the transmembrane region, and there are three helical structures in the secondary structure. Finally, this paper summarizes the status and function of Glycyrrhiza uralensis Fisch in the development of traditional Chinese medicine.
