Procedure for a phosphate-free ATP-regeneration from sucrose and pyrophosphate

Ref-Nr: TA-2387


Kurzfassung

Procedure for a phosphate-free ATP-regeneration from sucrose and pyrophosphate


Hintergrund

Adenosine triphosphate (ATP) is a broadly used co-factor for the synthesis of fine chemicals, pharmaceuticals, and biopolymers by biotransformation and biocatalysis. Since high concentrations of ATP and its by-product adenosine diphosphate (ADP) limit many biocatalytic processes, ATP regeneration is applied. This reduces the concentration and the overall amount of ATP and saves costs. In addition, labor- and cost-intensive product purification and unstable phosphate donors limit actual ATP-regeneration systems.

Lösung

Our procedure uses the energy-rich compounds pyrophosphate (PPi) and sucrose to generate ATP from ADP. For that, the enzyme Sucrose Synthase synthesize adenosine diphosphate-glucose (ADP-Glc) and fructose from ADP and sucrose. The enzyme ADP-Glucose Pyrophosphorylase processes ADP-Glc and PPi to generate ATP and glucose-1-phosphate. PPi is not added to the reaction, but can be used by every PPi generating reaction.


Vorteile

  • regeneration system based on low-cost feedstock
  •  PPi is directly recycled in the process
  • ATP-dependent enzyme cascades are stoichiometrically phosphate-free
  • Simplified product purification
