3.1.3.72
Ca2+
activates at a concentration equal to the substrate, but higher concentrations result in the precipitation of the substrate as calcium phytate and strongly inhibit enzyme activity, 10 mM EGTA prevents the calcium effect

3.1.3.72
Ca2+
activates, enzyme retains low level of activity even in Ca2+-free medium
663772
3.1.3.72
Ca2+
at concentrations equimolar to the substrate: 313% activation, but inhibitory at higher concentrations
