Cyanobacteria are a compact group of great ecological and biotechnological interest. We are using the unicellular cyanobacterium Synechococcus elongatus PCC 7942 as a model system in the following research lines:
Line 1
The cyanobacterial nitrogen interaction network
  A complex network of protein interactions allows cyanobacteria to control nitrogen metabolism in response to the intracellular nitrogen to carbon balance. PipX, a protein identified by us, is a multifunctional protein that forms complexes with the two nitrogen regulators PII and NtcA according to the 2-oxoglutarate levels. We are studying the molecular details and consequences of the complex protein interaction network in which these protein work.
