Effects of different cations on the activity of the purified recombinant AgaV^a

Cation	Relative activity (%) of AgaV at cation concn of:
	1 mM	10 mM	100 mM
Na+	170	206	340
K+	151	205	252
Ca2+	108	107	1.2
Co2+	104	0	0
Fe2+	62	0	0
Mg2+	241	137	45
Mn2+	0.64	0	0

^aThe activities are expressed as percentages of the enzyme activity measured in 50 mM sodium phosphate buffer (pH 7.0) alone.
