22.10.2025 Being lazy is not always bad: Cyclic di-AMP signaling in cyanobacteria

Prof. Khaled Selim, giving a talk in our Speaker Series, and his early-Tuesday audience kept things active, still.

On 21 October, we welcomed Khaled Selim to RTG 2937, who is Junior Professor at the Institute for Phototroph Microbiology of Heinrich Heine University Düsseldorf. His research group investigates the metabolism and the underlying signalling and transport mechanisms of organisms that use light as an energy source. The group focusses on the molecular and structural mechanisms by which photoautotrophic organisms coordinate their central carbon and nitrogen metabolism. The particular focus is on the control of CO2 metabolism using specific signalling proteins in cyanobacteria. The underlying, newly discovered PII signalling proteins link the perception of carbon resources on the one hand with that of energy sources, i.e. light, on the other. Read more about Kahled Selim and his distinctions and rewards here.

Thank you for the impulses you gave us relating to light and darkness and associated metabolic changes, Khaled! We were very happy to welcome you to Marburg.
