Abstract
Abstract Polyphosphate kinases (PPKs) have emerged as valuable candidates to address the unmet need for scalable recycling of the common enzyme cofactor adenosine‐5’‐triphosphate (ATP) because they use cheap, freely available and stable polyphosphate (polyP) salts as the phosphate donor. The aim of this review is not only to present recent efforts in the characterisation of PPKs but also to provide an overview of the challenges associated with their implementation in chemical manufacturing. In assessing the current status of polyP‐driven biocatalysts, we identify gaps that need to be filled for successful adoption of these biocatalysts in industry. Guidelines for a wider adoption of PPKs are also provided.
