Structure analysis of metagenomic xylanolytic enzymes. The ESPRipt analysis showing the conserved motifs for (A) GH-10 (WDVVNEI/A and TEL/MDM/I), (B) GH-11 (PLY/AEYYI/VE/D and ATEGYQ) endoxylanases, and (C) GH-43 (DDDG and LFYI). The GH-10 and GH-11 xylanases exhibited conserved motifs having highly conserved catalytic glutamate (E) and aspartate (D) residues. The signature structure of metagenomic GH-10 (Accession number: ADK78237.1), GH-11 (accession number: AQQ74873.1), and GH-43 (accession number: AFE48532.1) enzymes.
