Use of an Escherichia coli recombinant producing thermostable polyphosphate kinase as an ATP regenerator to produce fructose 1,6-diphosphate.

Heat-treated Escherichia coli producing Thermus polyphosphate kinase regenerated ATP by using exogenous polyphosphate. This recombinant could be used as a platform to produce valuable compounds in combination with thermostable phosphorylating or energy-requiring enzymes. In this work, we demonstrated the production of fructose 1,6-diphosphate from fructose and polyphosphate.
