Gene Expression and Molecular Characterization of a Xylanase from Chicken Cecum Metagenome

Figure 2

Phylogenetic analysis based on the amino acid sequence of and related GH10 family xylanases. The phylogenetic tree was constructed using the neighbor joining method (CLC Main Workbench version 7.7). The lengths of the branches indicate the relative divergence among amino acid sequences. The percentage bootstrap values based on 1,000 bootstrap replications are shown at the nodes. Xylanases of Sphingobacterium sp. TN19 and Sphingobacterium sp. HP455 are used as outgroups. Accession numbers of the xylanase amino acid sequences are shown with the names of the host organisms. The scale bar represents the number of changes per amino acid position.
