LITERATURE
K+
K+ ion at the GTP binding site allows the positioning of one water molecule that interacts with catalytic residues D235 and D238, K+ ion stabilizes dimer (molecular dynamics simulations)
Na+
Na+ destabilizes the dimer and does not allow the positioning of the catalytic water molecule (molecular dynamics simulations)
