Interaction stabilizing GDP and magnesium in the LdRab5a crystal structure. GDP (yellow) in LdRab5a with neighboring residues (C atoms in gray) that interact through hydrogen bonds that help to stabilize both GDP and the magnesium ion. Mg1A (olive) is hexacoordinated by water molecules (teal), Ser27 and the O atoms of the terminal β-phosphate group of GDP. |
