Deletion of the gene for a cyanobacterial ribosome-associated protein affects the carbon/nitrogen metabolism

Nouha Abdelaziz, Alexander Kraus, Stefan Timm, Friedel Drepper, Viktoria Reimann, Marc Broghammer, Bettina Liebowitz Knapp, Antonio López‐Lozano, Ravi Shankar Ojha, Bettina Siebers, Michael Y. Galperin, José Manuel Garcı́a-Fernández, Manuel Brenes‐Álvarez, Pitter F. Huesgen, Martin Hagemann, Wolfgang R. Hess

This paper characterizes the function of the cyanobacterial gene ssr3189 by analyzing its deletion mutant, revealing its role in linking translation with metabolic control and RNA decay.

Story about honest mistakes: The cyanobacterium Synechocystis has a promiscuous Entner-Doudoroff (ED) aldolase but no functional ED pathway.

Ravi Shankar Ojha, Marius L. Theune, Ruben Fritsche, Alexander Makowka, Marko Boehm, Carmen Peraglie, Christopher Bräsen, Jacky L. Snoep, Martin Hagemann, Bettina Siebers, Kirstin Gutekunst

This study revisits the claim of the Entner-Doudoroff pathway in Synechocystis, showing that while the aldolase is present, the full pathway is absent due to missing enzymes and experimental errors.

Fructose-1,6-bisphosphatase (FBPase) fine-tunes heterotrophic growth in cyanobacteria

Frauke Caliebe, Ravi Shankar Ojha, Marco Gruber, Marko Boehm, Lu Shen, Christopher Bräsen, Jacky L. Snoep, Karl Forchhammer, Martin Hagemann, Bettina Siebers, Kirstin Gutekunst

This study identifies FBPase in Synechocystis as a monofunctional enzyme that supports heterotrophic growth without redox regulation, distinct from the bifunctional F/SBPase.
