We are seeking to fill a part-time position (25.8895 hours/week = 65%) as soon as possible .
PhD student (m/f/d) in chemical biology with a research focus on target identification in antibiotic research
The threat posed by bacterial infections is a steadily growing danger to global health. Resistant strains of bacteria, such as MRSA or XDR-TB, are spreading further and increasingly evading conventional antibiotic therapies. Therefore, chemotherapeutic agents with novel mechanisms of action are urgently needed to enable effective treatments against these resistant strains. An important resource for the development of such new drugs are bioactive natural products, which can originate from a wide variety of organisms, such as bacteria, fungi, or plants. To fully exploit the potential of these natural products, it is essential to elucidate their biological mechanisms of action. The MCLS develops and utilizes innovative methods of chemical biology in combination with state-of-the-art mass spectrometry-based analysis to identify the molecular targets of newly isolated natural products and thus elucidate their mechanisms of action for a translational research approach.
To strengthen our team, we are seeking a PhD student (m/f/d) to start as soon as possible. The PhD research will focus on identifying potential protein targets of naturally occurring polyaromatic anthraquinones in Bacillus subtilis and pathogenic bacteria. This includes the chemical synthesis of these natural products and their derivatization, with the aim of generating chemical probes for use in MS-based enrichment experiments. The potential protein targets identified in this way will then be validated and further characterized using biochemical and molecular biological methods.
