Since the extracellular amylase from ~~_Se1gQ1Y~!s~§ had been characterized as a Ca-dependent enzyme, we wanted to determine the function and specificity of this ion, and it's possible significance for the thermophilic properties of the enzyme. The first question concerned the substitution of Ca with regard to the activity at 70 C. Our data show that Sr or other divalent cations can only to a limited extent replace Ca, and that only in presence of Ca full activity can be achieved. When the… CONTINUE READING
