additional information the enzyme prefers ADP as phosphoryl donor, but ADP can be replaced by ATP resulting in a 5fold lower activity. The enzyme catalyzes the phosphorylation of fructose 6-phosphate and dephosphorylation of fructose 1,6-bisphosphate. In addition, it is able to phosphorylate D-glucose and nucleosides but with a much lower rate compared to that of fructose 6-phosphate, the enzyme shows 450fold lower activity with D-glucose (cf. EC 2.7.1.147) compared to that with fructose 6-phosphate. Only 20% phosphofructokinase activity is observed in the presence of 2 mM ATP compared to 100% in the presence of equimolar ADP. No significant activity is detected in the presence of other phosphoryl donors examined. For the phosphoryl acceptor specificity, a number of alternative substrates including nucleosides, sugars and sugar phosphates are examined. Among the nucleoside substrates, adenosine shows 12%, 2-deoxyadenosine 17.5%, and thymidine 18% consumption of ADP. Among sugars and sugar phosphates, 22% and 5% relative activities can be observed with glucose and ribose 5-phosphate, respectively. Substrate specificity, overview Thermococcus kodakarensis ?
