The Deutsche Forschungsgemeinschaft (DFG) is the self-governing organisation for science and research in Germany. It serves all branches of science and the humanities. In organisational terms, the DFG is an association under private law. Its membership consists of German research universities, non-university research institutions, scientific associations and the Academies of Science and the Humanities.

Cyanobacteria are the only prokaryotes performing oxygenic photosynthesis. Theyhad and have tremendous influence on the biogeochemical cycles on Earth. Recently,cyanobacteria are increasingly investigated as cell factories for a sustainableeconomy. Despite their global, environmental and rising economic importance, ourknowledge on the regulation of their primary metabolism is fragmented.Cyanobacteria switch between photoautotrophic and heterotrophic modes ofmetabolism during day/night cycles or ...

Abstract The enzyme Glucose-1-phosphate adenylyltransferase (GlgC, EC:2.7.7.27) catalyses the first step in glycogen synthesis by converting glucose-1-phosphate into ADP-Glucose, which is added in turn to a growing glycogen chain by glycogen synthases. Thus far, the in vitro study of GlgC were mainly performed using colorimetric or radiolabel-based phosphate release assays, limiting the option for analysing this reaction. With this work, we present a novel in vitro continuous assay coupling the ...
