Conformational change induced by d-xylose binding and release. (A) Superimposition of the structures of d-xylose–bound XylFII-LytSN-xyl and d-xylose-free XylFII-LytSN-apo (containing the D103A mutation). XylFII-LytSN-xyl is shown in gray, and XylFII and LytSN in the XylFII-LytSN-apo complex are shown in blue and orange, respectively. (B) Conformational change of XylFII induced by d-xylose binding and release. The CTD of XylFII underwent a 40-degree rotation during d-xylose binding and release.
