Superposition of the BT2081 C-terminal domain (yellow) with two representative top structural neighbors as assessed by FATCAT: the catalytic module of a Bacillus 1,3–1,4-β-glucanase (red; PDB code 1byh
) and CBM29 of a mannanase from T. polysaccharolyticum (green; PDB code 2zew
). (a) View from above the convex surface of the β-jelly-roll core, highlighting the conserved calcium ion represented as spheres and circled. (b) View from above the concave surface of the β-jelly-roll core, highlighting the extended loop regions of BT2081 (circled) which help to form a pocket on the concave surface of the core. |
