Abstract: "To understand ATP permeation through VDAC, [investigators] solved the crystal structure of mouse VDAC1 (mVDAC1) in the presence of ATP, revealing a low-affinity binding site. Guided by these coordinates, [they] initiated hundreds of molecular dynamics simulations to construct a Markov state model of ATP permeation." |

P.628 left column 2nd paragraph: "[Investigators’] calculations recapitulate the experimental finding that VDAC1 selectivity is ~5 (Cl−/K+) in physiological salt concentrations [primary source] and 1.7–1.9 under a 1.0–0.1 M KCl gradient [ref 15]." |
