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

Figure 1

Amino acid sequence alignment of with closely related GH10 family beta-xylanases from Prevotella bryantii B14 (CAD21011), Prevotella ruminicola B(1)4 (P48789), Prevotella copri DSM 18205 (WP_006847660), Prevotella dentalis DSM 3688 (AGB29059), Paraglaciecola mesophila KMM 241 (ACN76857), Thermobacillus xylanilyticus D3 (CAA76420), and Paenibacillus barcinonensis BP-23 (O69231). The highly conserved motifs DVVNE and TEXD are shown in boxes, each containing an active site glutamate (marked with an asterisk) and an invariant asparagine residue (marked with an arrow) preceding the active site glutamate in the first box.
