Xylanase immediately hydrolysis xylanase main chain of β-1， 4 - glucoside bond， with the five-carbon sugar linked to the Widely used in industrial production areas， combined with the cellulose can be used to transform the use of environment-friendly fuel - ethanol， use of natural renewable resources: cellulose and However， industrial production often harsh conditions， making use of Xylanase be greatly In addition to screening the appropriate strains， people want to use means of protein engineering xylanase This requires understanding of protein function with protein sequence and structure of space-related knowledgeBioinformatics is an emerging， and in the early stages of development of biological systems in the phenomenon of scientific information， it is multidisciplinary cross-product of biological， mathematics， physics， computer science， information science， and other fields， biological information To the medium of the Internet， databases as the carrier， the use of mathematical knowledge to establish model and a computer as a tool for Experimental Biology in the large number of biological data storage， retrieval， processing and analysis， and knowledge of the biology Interpretation of results， and eventually revealed deposits in the DNA sequence and protein amino acid sequence of universal， the authenticity of genetic The main topic of bioinformatics analysis xylanase gene and protein sequences， understanding and xylanase Xylanase dynamic and research on domestic and international significance， using molecular biology and bioinformatics with the knowledge and application of software analysis Data， the first in the Entrez enquiry system in the xylanase enzyme gene and protein sequences a lot of enquiries， and relevant biological information data record， followed by the one hand， the use of bioinformatics software to these conservative parts of the sequence analysis， On the other hand analysis on the sequence of evolutionary origin， on this basis， the proposed transformation of xylanase gene
