PhD Candidate in the Design and Synthesis of Pyrophosphate Mimetics to Study Enzymes Involved in Natural ADP-Ribosylation

The Faculty of Science Leiden and Leiden Institute of Chemistry are looking for a PhD candidate in the design and synthesis of pyrophosphate mimetics to study enzymes involved in natural ADP-ribosylation.

ADP-ribosylation (ADPr) is a common but poorly understood post-translational modification of proteins, with a confirmed role in various physiological processes such as DNA repair and antiviral defense. Protein targets are enzymatically modified with ADP-ribose by ADP-ribosyltransferases of the PARP family, while ADP-ribosylhydrolases remove the ADP-ribose residue. Understanding the detailed mechanisms of such modification and demodification is vital to uncover the regulatory functions of ADP-ribosylation and to develop innovative therapies for cancer, viral infections, neurodegenerative, and autoimmune diseases.

The goal of the proposed research is to design and synthesize a range of well-defined substrate mimics, inhibitors, and probes to target various ADP-ribosyltransferases and ADP-ribosyl hydrolases, to enable a better understanding of their catalytic mechanism, specificity, and regulatory role. The project will be carried out as a collaborative effort with researchers from the fields of chemical and structural biology of ADP-ribosylation.

Work and profile 
We are looking for a candidate with a strong synthetic organic chemistry background with a keen interest in (chemical) biology and structural biology, who is a real team player and open to collaborating in an international and interdisciplinary manner. 

• A Master’s degree in chemistry
• Experience in synthetic bioorganic chemistry
• Experience with the synthesis of nucleic acid derivatives, carbohydrates or phosphates is desirable
• Affinity with biological chemistry
• High motivation for interdisciplenary research
• Excellent command of written and spoken English
• A strong teamwork mentality

Description of organisation and terms of employment
The position starts on 1 January, 2026. We offer a position for 12 months and upon satisfactory performance to be extended for three more years.
