Popis: The dependence of the initial rate on the concentration of MgATP 2− and fructose-6-phosphate, its behaviour with the alternative substrates MgGTP 2− and MgITP 2- and the inhibition patterns by its products, suggest that the reaction catalysed by phosphofructokinase from the mantle tissue of the mussel Mytilus galloprovincialis Lmk, involves a Theorell-Chance mechanism in which MgATP 2− is the first substrate to bind to the enzyme.
