Overview of the IaGal structure. A The overall structure of the IaGal catalytic domain. Secondary structural elements are coloured (α-helices red, and β-sheets yellow). The catalytic acid/base (Glu165) and catalytic nucleophile (Glu266) are shown in sticks. Trp115 and Trp338 correspond to the − 2 and − 3 subsites, respectively. The calcium binding site is also highlighted. B The calcium binding site of IaGal (PDB ID: 7OSK, green) compared to that from the bacterial enzyme BlGal (PDB ID: 1UR0, magenta)
