Fig. 3: Comparison of active site volumes in the closed substrate-bound state.
From: Structural insights into S-lignin O-demethylation via a rare class of heme peroxygenase enzymes
Surface rendering of a a slab view of the active site of SyoA (purple) bound to syringol (yellow/red large spheres) and b wireframe surface of the active site pocket showing the position of the heme (white sticks), syringol (yellow/red) and waters (small red spheres) that occupy the pocket. Surface rendering of c a slab view of the active site of SyoA (pink) bound to 4-methylsyringol (light red/red large spheres) and d wireframe surface of the active site pocket showing the heme (white sticks), 4-methylsyringol (light red/red) and waters (small red spheres). Surface renders (a, c) are clipped through the center of SyoA at the position of the substrate. The second image (b, d) is rotated 90° clockwise about the y-axis relative to the first pane.
