Figure 3.

The structural model of the Far Eastern holothurian mannan-binding hybrid lectin MBL-AJ monomer with the alkaline phosphatase CmAP (CmAP/MBL-AJ). C-terminal end of the CmAP subunit is linked via flexible linker (G₄S)₃ with N-terminal end of the lectin MBL-AJ subunit that allow to function domains independently from each other.⁴⁴ Three spheres in CmAP module indicate 2 ions Zn²⁺ and one ion Mg²⁺; one sphere in MBL-AJ indicates ion Ca²⁺. α-Helixes and β-strands are shown as ribbons. Unordered structures are shown as threads.
