Green fluorescent proteins (GFPs) are invaluable tools for modern cell biology. Even though many properties of GFP have been successfully engineered, a GFP retaining brightness at low pH has not emerged. This limits the use of GFP in quantitative studies performed in fluctuating or acidic conditions. We report the engineering and characterisation of tandem(More)
Chiral resolutions of racemic mixtures are limited to a theoretical yield of 50 %. This yield can be doubled by integration of a step-wise or continuous racemization of the non-desired enantiomer. Many of the different routes along which the racemization step can be conducted require harsh treatments and are therefore often incompatible with the highly(More)
Cell-free biosynthesis in the form of in vitro multi-enzyme reaction networks or enzyme cascade reactions emerges as a promising tool to carry out complex catalysis in one-step, one-vessel settings. It combines the advantages of well-established in vitro biocatalysis with the power of multi-step in vivo pathways. Such cascades have been successfully applied(More)
