Abstract
The Na+/Ca2+ exchangers (NCXs) modulate the Ca2+ signaling and homeostasis in health and disease. The transport cycle turnover rates (kcat) and the kcat/Km values of eukaryotic NCXs are ~104-times higher than those of prokaryotic NCXs. Three ion-coordinating residues (out of twelve) differ between eukaryotic NCXs and NCX_Mj. The replacement of three ion-coordinating residues in NCX_Mj does not increase kcat, probably due to the structural...
