Commentary
Reference
Ca2+
activated by physiological concentration, maximal activity at 2 mM
Ca2+
no activity in the presence of 1.0 and 5.0 mM Ca2+
Cd2+
no activity in the presence of 1.0 mM Cd2+, weak enzyme activation at 5 mM (4.% compared to 1.5 mM Mn2+)
Co2+
5 mM, 42% of the activity with Mg2+
Co2+
60% of activity
Co2+
about 50% of the activity with Mn2+. In the presence of Mn2+, PrpA hydrolyzes P1,P3-bis(5'-adenosyl)tetraphosphate mainly into AMP and ATP, whereas in the presence of Co2+, PrpA hydrolyzes P1,P3-bis(5'-adenosyl)tetraphosphate into two molecules of ADP, reaction of EC 3.6.1.17
Co2+
divalent cation required, 20% of maximal activity in presence of 1 mM Co2+
Co2+
the enzyme is dependent on divalent cations
Co2+
weak stimulation
Mg2+
