Metals/Ions

Metals/Ions	Comment	Organism	Structure
Ca2+	alpha-linolenic acid stimulates activity in presence of CaCl2	Spinacia oleracea
K+	alpha-linolenic acid stimulates in presence of high concentrations of KCl	Spinacia oleracea
Mg2+	alpha-linolenic acid causes drastic increase in activity under limiting concentrations of MgCl2, without affecting its maximum activity at higher MgCl2 concentration, free alpha-linolenic acid alone does not affect the activity	Spinacia oleracea
Mg2+	unsaturated 16- and 18-carbon fatty acids stimulate in presence of MgCl2	Spinacia oleracea
Mg2+	EDTA inhibits stimulation	Spinacia oleracea
Mn2+	alpha-linolenic acid stimulates activity in presence of MnCl2	Spinacia oleracea
