In human cells, P5B‐ATPases execute export of spermine from lysosomes to the cytosol, but the mechanisms of spermine recognition, uptake and transport remain elusive. Here the authors present cryo‐EM structures of a yeast homolog of human ATP13A2‐5, Ypk9, which depict three separate transport cycle intermediates, including spermine‐bound conformations
