Abstract

•
Phospholipid-binding abilities of mpox virus A7 protein and its truncations are investigated.
•
The structures of the N-terminal truncations of A7 protein (A7N₁₂₁ and A7N₁₃₇) are determined.
•
Conformational changes of the conserved linking helix in A7 are illustrated.
•
A structural model of the full-length A7 protein is proposed.
