2.2.1.1 | Ca2+ | in the presence of free Ca2+, the equivalence of the two active centers of the enzyme is lost. Negative cooperativity is induced on binding of either xylulose 5-phosphate or ribose 5-phosphate, whereupon the catalytic conversion of the bound substrates causes the interaction between the centers to become positively cooperative. Enzyme total activity increases in presence of Ca2+ | Saccharomyces cerevisiae |
