3.6.1.25	ATP + H2O	low affinity	?	-	?
3.6.1.25	ATP + H2O	-	ADP + phosphate	-	?
3.6.1.25	more	the enzyme has low affinity for CTP, ATP or thiamine triphosphate. Nucleoside triphosphatase activity is negligible in the presence of 5 mM Mg2+, but a small activity is observed in the presence of 1 mM Mn2+, in particular with GTP. Guanosine 5-tetraphosphate and long chain polyphosphate (containing about 65 phosphate residues) are not hydrolyzed. The enzyme has no adenylyl cyclase activity	?	-	?
3.6.1.25	more	TTM3 is a protein with high triphosphatase activity (binding both tripolyphosphate and ATP) and low adenylyl cyclase activity	?	-	-
3.6.1.25	more	TTM dooes not produce any cyclic nucleotides. With substrate triphosphate, TTM is 19fold more reactive than with NTPs	?	-	-
3.6.1.25	tetraphosphate + 2 H2O	-	diphosphate + 2 phosphate	-	?
3.6.1.25	triphosphate + H2O	-	diphosphate + phosphate	-	?
3.6.1.25	triphosphate + H2O	involved in phosphorous and energy exchange of mitochondria	diphosphate + phosphate	-	?
3.6.1.25	triphosphate + H2O	involved in transcription termination	diphosphate + phosphate	-	?
3.6.1.25	tripolyphosphate + H2O	very good substrate with Mg2+ as activator. The enzyme has a strong preference for linear tripolyphosphate compared with cyclic trimetaphosphate and to the linear tetraphosphate	diphosphate + phosphate	-	?
