SARS‐CoV‐2 nucleocapsid (N) protein plays essential roles in many steps of the viral life cycle, thus representing a key drug target. N protein contains the folded N‐/C‐terminal domains (NTD/CTD) and three intrinsically disordered regions, while its functions including liquid–liquid phase separation (LLPS) depend on the capacity in binding various viral/host‐cell RNA/DNA of diverse sequences. Previously NTD was established to bind various RNA/DNA while CTD to dimerize/oligomerize for forming high‐order structures. By NMR, here for the first time we decrypt that CTD is not only capable of binding S2m, a specific probe derived from SARS‐CoV‐2 gRNA but with the affinity even higher than that of NTD. Very unexpectedly, ATP, the universal energy currency for all living cells with high cellular concentrations (2–16 mM), specifically binds CTD with Kd of 1.49 ± 0.28 mM. Strikingly, the ATP‐binding residues of NTD/CTD are identical in the SARS‐CoV‐2 variants while ATP and S2m interplay in binding NTD/CTD, as well as in modulating LLPS critical for the viral life cycle. Results together not only define CTD as a novel binding domain for ATP and nucleic acid, but enforce our previous proposal that ATP has been evolutionarily exploited by SARS‐CoV‐2 to complete its life cycle in the host cell. Most importantly, the unique ATP‐binding pockets on NTD/CTD may offer promising targets for design of specific anti‐SARS‐CoV‐2 molecules to fight the pandemic. Fundamentally, ATP emerges to act at mM as a cellular factor to control the interface between the host cell and virus lacking the ability to generate ATP.
