[On the enzymatic breakdown of tripolyphosphate and diphosphate in comminuted meat. VIII. Influence of divalent cations on the tripolyphosphatase activity of muscle tissue (author's transl)].
The tripolyphosphatase of comminuted muscle tissue is activated by MgC1(2) and ethylenediamine tetraacetate and inhibited by CaC1(2) and diphosphate. These results are discussed with reference to the formation of an inactive enzyme-substrate complex.
