Bioinformatics Analysis of Xylanase xynMF13-GH10 Gene from Mangrove Fungi

[Objectives]The paper was to analyze and predict the structure and characteristics of xylanase xynMF13-GH10 gene and its encoded protein.[Methods]xynMF13-GH10 gene was predicted by NCBI and various information analysis tools in ExPASy website,as well as SignaIP 5.0,DNAman,TMHMM,SOPMA and SWISS-Model,and the characteristics and functions of protein structure encoded by the gene were predicted.[Results]The gene is 1332 bp in length,the coding region is 1-1332 bp,and the gene encodes 443 amino acids.The xynMF13-GH10 gene has high homology with xylanase in many species,and it has the highest homology with Paraphaeosphaeria sporulosa endoxylanase-like protein,with the consistency reaching 78.91%and e-value reaching 2e-159.The secondary structure consists of 48.31%random curl,30.25%α-helix structure,16.70%extended chain and 4.74%β-corner.[Conclusions]The results provide a reference for revealing the physiological function and expression regulation mechanism of xynMF13-GH10 gene in the future.
