Substrate specificity of the phosphatase activities of the TON_1705- and TON_1706-encoded proteins

Substratea	Activityb
	TON_1705	TON_1706
Pyrophosphate	100	<1
PAP	ND	100
PAPS	ND	23
ADP	5	<1
3′-AMP	4	<1

AMP	1	<1
Polyphosphate	<1	<1

Fructose 1,6-bisphosphate	ND	<1
d-myo-Inositol 1-monophosphate	ND	<1

^aSubstrates were used at concentrations of 1.0 mM and 0.5 mM for TON_1705 and TON_1706, respectively.

^bActivity is indicated by considering the relative activities of TON_1705 and TON_1706 toward pyrophosphate and PAP to be 100%, which are equivalent to specific activities of 0.16 μmol min⁻¹ mg⁻¹ and 483.6 μmol min⁻¹ mg⁻¹, respectively. ND, not determined.
