SCyCode The Autotrophy-Heterotrophy Switch in Cyanobacteria: Coherent Decision-Making at Multiple Regulatory Layers
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 under specific environmental conditions withthe enzymatic capacity for both life-styles being present in one cell. It is notunderstood how this remarkable metabolic plasticity, which requires coherentdecisions at multiple layers in response to different external and internal signals, isachieved. Our research network aims at answering this major unsolved question. Wewill address the function and control of key enzymes, pathways and regulators of Cmetabolismand their interplay to unveil the (hidden) regulatory layers that organizethe central metabolic routes. Therefore, the consortium, composed of experts withcomplementary skills, will use the model strain Synechocystis sp. PCC 6803 for an integrative application of advanced biochemical, transcriptomic, fluxomic, andproteomic methods.

Analysis of the sequences of PGM1 from several Synechocystis strains revealed a different annotation for Synechocystis sp. PCC 6803, which included a 16-amino acid N-terminal extension that is missing in the other strains. Additionally, the experimentally validated transcriptional start site from Synechocystis sp. PCC 6803 suggests a shorter open reading frame for PGM1, with Met 17 as putative translational start site. To clarify if the N-terminal extension is an annotation error, we prepared ...
To test the effecf of phosphorylation of Ser 47 on PGM1 activity, this residue was exchanged for Ala and Asp and the activity of the recombinant proteins was measured in vitro.
