====== Manganese(II) - ED[PY2]WaWa ======

In Pyruvate Kinase manganese(II) mediates the allosteric communication between the phosphoenolpyruvate and fructose-1,6-bisphosphate.
Crystal structures suggest that manganese(II) bonds to aspartate, glutamate and the oxygen from a carbonyl and carboxylate groups from a pyruvate ligand.
A water molecule is referred as participating in the octahedral coordination of manganese(II).
