Fig. 3. Structural comparison reveals the conformational changes of V1 domain owing to the mEAK7 engagement.
a Structural comparison of ABclosed to mEAK7 bound ABsemi. b Structural comparison of ABopen to mEAK7 bound ABsemi. c The cartoon model explains the uniqueness of the mEAK7 binding site. d–f The conformational changes of V-ATPase compared to apo bovine V-ATPase. g–i The conformational changes of V-ATPase compared to SidK-bound human V-ATPase. All conformational changes are indicated by either a red oval or arrows.
