Co2+ | nerolidol synthase is completely inactive in the absence of added divalent metal ion. Mg2+ is most effective. Co2+ shows 11% of the activity compared to Mg2+ | Zea mays | |
Cu2+ | nerolidol synthase is completely inactive in the absence of added divalent metal ion. Mg2+ is most effective. Cu2+ shows 12% of the activity compared to Mg2+ | Zea mays | |
Mg2+ | nerolidol synthase is completely inactive in the absence of added divalent metal ion. Mg2+ is most effective. Other divalent cations are less effective in supporting catalysis. Metal ions in order of edcreasing efficiency: Mg2+, Mn2+, Co2+, Cu2+, Ni2+, Zn2+. KM-value for Mg2+ is 0.125 mM | Zea mays | |
Mn2+ | nerolidol synthase is completely inactive in the absence of added divalent metal ion. Mn2+ is half as effective as Mg2+ at 1 mM, inhibits at higher concentrations | Zea mays | |
Ni2+ | nerolidol synthase is completely inactive in the absence of added divalent metal ion. Mg2+ is most effective. Ni2+ shows 17% of the activity compared to Mg2+ | Zea mays |
