3.1.3.11 Ca2+ at low concentrations 653727 3.1.3.11 Ca2+ regulation of complex of enzyme with alodolase. Elevated Ca2+ concentration decreases association constant of enzyme-aldolase complex and enzyme-alpha-actinin complex. Release of Ca2+ during muscle contraction may result in inhibition of glyconeogenesis and in the acceleration of glycolysis 664951 3.1.3.11 Ca2+ requied for activation of FBPase by 2-Cys peroxiredoxin 677956 3.1.3.11 Co2+ activates 749848 3.1.3.11 Co2+ slight activation 170798 3.1.3.11 Cs+ enhances activity 170739 3.1.3.11 Cu2+ stimulation increases in the order Mg2+, Mn2+, Zn2+, Cu2+. Mg2+ stimulates below 5 mM, inhibits above 10 mM 730360 3.1.3.11 dithiothreitol the recombinant enzyme is activated 653727 3.1.3.11 Hg2+ low concentrations stimulate the oxidized enzyme form, but not the reduced enzyme form many hundred-fold. Half-maximal stimulation at 0.2 femtoM: Hg2+ stimulates by binding to an enzyme thiol group, thereby stabilizing the oxidized enzyme in an active conformation 170791 3.1.3.11 K+ - 652041
