Main interactions between sucrose and amino acid residues in the active site.

<p>Map of hydrogen bonding interactions occurring between ΔN123-GBD-CD2 and sucrose in clusters taken from the energy landscape basins (ΔG < 100 J. mol^-1) (A). The x and y axis indicate the atoms from sucrose and the enzyme involved in hydrogen bonding interactions. The color code indicates the hydrogen bond occurrence percentage over the cluster. In (B) panel are illustrated the important interactions observed between sucrose and amino acids in the catalytic pocket.
