Depicted are electrostatic potentials calculated in APBS (Jurrus et al, 2018), mapped onto molecular surfaces calculated in Pymol for EcPPX1 (PDB-ID: 1U6Z), ScPPX1 (PDB-ID: 2QB7), FtPPK2 (PDB-ID: 5LLF), ScVTC4 (PDB-ID: 3G3Q), EcPPK1 (PDB-ID: 1XDP), and ygiF (PDB-ID: 5A61). Bound phosphates, sulfates, polyPs, and PPK1 substrate analogs are highlighted in bond representation.
