From: Non-enzymatic formation of isoprene and 2-methyl-3-buten-2-ol (2-MBO) by manganese

Chemical structure of DMDP bound to MgCl2. The DMADP structure in the water at 313 K (40 °C) was simulated for 10 ns using the Amber software. One of the models showing attractive interaction of H7 and O3 with atom distance 2.2 Å was selected. Two Mn2+ bound to one DMADP molecule. Three negative charges of DMADP were stoichiometrically neutralized by 2 Mn2+, and one excess positive charge of Mn2+ was antagonized by one negative chloride ion. The atom labels were by the Amber program (AMBER 2016, Case et al. 201621, https://ambermd.org/index.php).
