Metals/Ions Comment Organism Structure
Mg2+ plasma membrane vesicles from the optic nerve accumulate Ca2+ in the presence of Mg2+ Sepioteuthis sepioidea
Na+ when an outwardly directed Na+ gradient is imposed on the plasma membrane vesicles from the optic nerve, they accumulate Ca2+ in the absence of Mg2+ and/or ATP. Km for Na+ is 74 mM Sepioteuthis sepioidea
