Job Description
Missions
The research for this position is to explore the genesis of oxygenic photosynthesis from an older form of photosynthesis that was non-oxygenic and based on sulfur oxidation. Some cyanobacteria are able to express simultaneously a variant of the oxygen-evolving enzyme Photosystem II (PSII) and proteins involved in the sulfur metabolism. Among these proteins, we have identified the flavoprotein sulfide-quinone oxidoreductase (SQR) and a cytochrome-c (cyt-c) with a rare heme-axial ligation that appears to be involved in catalytic sulfur chemistry. When the PSII variant, the SQR and the cyt-c are express, cells grow in presence of sulfide suggesting that these cells have a set of characteristics that confer them a selective advantage in more reducing environment, condition that resembles an ancient time in Earth's history when aquatic environment was not completely oxygenated.
Activity
The candidate will focus on the physiological and biochemical characterization of this intermediate state of evolution of photosynthesis where a variant of the oxygen-evolving enzyme PSII and proteins involved in the sulfur metabolism are expressed together. Our aim is to identify the network of proteins that allowed organisms to evolve oxygenic photosynthesis.
The candidate will interact with leading authorities in photosynthesis and have access to state-at-the art technical facilities.
Your Profil
Skills
We are seeking a motivated candidate with training in biochemistry and physiology of cyanobacteria ideally with experience in the following area: cyanobacteria cells culture, protein biochemical techniques such as protein purification and protein interaction methods. Experience in molecular biology of cyanobacteria is a plus.
Your Work Environment
The position is for a postdoctoral researcher for two years to start as soon as possible. The salary and benefits are competitive. The laboratory is located at the Institute for Integrative Biology of the Cell at the CEA Saclay 30 min from Paris, a world cultural center.
