New publication

Our third paper on the chemical origins of life is published in Nature. We show that ferrous iron promotes a one-pot reaction network that resembles the Krebs cycle and amino acid synthesis, starting from just pyruvate and glyoxylate. These enzyme-free reactions could have been a precursor to biological metabolism. Congrats to Kamila and Sreejith! Free read-only version here. Paywall version here.

New publication

The second paper from our collaboration with the Ebbesen group describing how running a reaction between two appropriately-spaced mirrors can change its selectivity has appeared in Science. Congrats to Lucas from our lab and to all who participated from the Ebbesen group!

Dr. Vuk Vuković

Congrats to Vuk Vuković on successfully defending his thesis! He is the fourth PhD student to graduate from the group. After throwing a big party with friends from all over Europe, he will return to the lab for three months before heading off to his next adventure. Special thanks to jury members Prof. Vincent Gandon, Prof. Sébastien Thibaudeau and Dr. Joanna Wencel-Delord.

 

PhD position Marie Curie ITN ProtoMet

ProtoMet (acronym of the project “Protometabolic pathways: exploring the chemical roots of systems biology” funded by European Union through the European Training Network H2020 Marie Sklodowska-Curie Actions (ITN) – GA n. 813873) will offer the opportunity to motivated international Early Stage Researchers (ESRs) to address the tremendous challenge of understanding how prebiotic chemistry gave rise to life by training a new generation of scientists to think big, but also to work methodically and logically alongside colleagues from academia and industry.

The goal of the project led by the University of Strasbourg (ESR2) is to identify potential catalytic feedback effects resulting from the products of a primitive metabolism. For instance, can short peptides, which are made from amino acids, enable ligand-accelerated catalysis in reactions that produce amino acids, such as in the metal-catalysed transamination of ketoacids? Can chirality be transmitted from peptide to amino acid, and if so, does this transmission exhibit non-linearity? These investigations will shed light on how a primitive metabolism can self-complexify before the onset of Darwinian evolution and may also provide insight into the origin of biological homochirality.

Your background: A master degree / level in chemistry. Possessing at least the B2 level of the CEFR (Common European Framework of Reference for Languages) in English.

How to Apply

Send detailed CV and motivation letter to moran@unistra.fr mentioning “Protomet PhD recruitment” in the subject. The deadline for application is January, 15th 2019.

Dr. Sreejith Varma

Congrats to Sreejith Varma on successfully defending his thesis! He is the third PhD student to graduate from the group. After a trip back to India, he will return to the lab for two months before heading off to a postdoc position at Charité Hospital in Berlin. Special thanks to jury members Prof. Marie-Christine Maurel, Dr. Cornelia Meinert and Prof. Peter Faller.
