Free Energy of Fructose-6-Phosphate and Glucose-6-Phosphate

Fructose-1,6-diphosphate can be converted to glucose-1-phosphate by three successive reactions:

Fructose 1,6 diphosphate + H20 ---> fructose-6-phosphate + Pi Keq= 607

Fructose-6-phosphate ---> glucose-6-phosphate G°= -410 cal/mol

Glucose-6-phosphate --->glucose-1-phosphate G°= 1750 cal/mol

Assuming 1 atm pressure, 25°C, R = 1.99cal/mol x deg C. From the above info what is the Keq and the deltaG° for the overall reaction?
