Crystal structures of Sinorhizobium meliloti polyphosphate kinase 2 [60]and their implications for polyphosphate synthesis. S. meliloti PPK2 contains four monomers. Each monomer contains two domains coloured in yellow and green connected by a flexible linker coloured in red. The coordinates were downloaded from Protein Data Bank (the corresponding PDB codes- 3CZQ) [63] and visualized by Visual Molecular Dynamics 1.9 [64] and POV-Ray [65].
