Stereoviews of superimpositions of SdCBAP complex structures.
A, CbA (yellow) and GlcA-GcL (cyan). B, CbA (yellow) and Glc-β1,3-GlcUA (magenta). C, CbA (yellow), Glc-β1,3-GlcUA (magenta thick sticks), and a GlcUA molecule modeled at subsite +1 by superimposing the C2–C6 atoms to CbA (magenta thin sticks). Hydrogen bonds present in the CbA, GlcA-GcL, and Glc-β1,3-GlcUA complex structures are shown as yellow, cyan, and magenta dashed lines, respectively.
