Fe2+ | Fe2+ also enhances the enzyme activity but to a lesser extent than Zn2+ | Thermococcus kodakarensis | |
Mn2+ | Mn2+ also enhances the enzyme activity but to a lesser extent than Zn2+ | Thermococcus kodakarensis | |
Zn2+ | addition of Zn2+ ions remarkably enhances the enzyme activity (more than 3fold at 0.2 mM) | Thermococcus kodakarensis |
