Synthetic biology of microbial natural products
The Bozhüyük group focuses on bacterial natural products, with unique structures and bioactive properties. The group studies modular assembly lines like polyketide synthases (PKSs) and non-ribosomal peptide synthetases (NRPSs), which produce many essential clinical agents – but are especially valuable to develop new anti-infectives. This group is located at the Helmholtz Institute for Pharmaceutical Research Saarland (HIPS) .
Proteome Analytics
Pathogenic bacteria and viruses utilize and manipulate cellular processes of our immune system. The identification of protein functions in the human immune system that decisively control the progression of infections constitutes the central aim of the research group Cellular Proteomics at the HZI.
Microbial Drugs
The majority of the medically important antibiotic drugs are derived from secondary metabolites, which are produced by bacteria and filamentous fungi. Despite intensive world-wide efforts using alternative approaches, no other concept could so far surpass the historically successful strategy to exploit biologically active natural products as candidates for anti-infective drugs. The recently observed, increasing resistance of the human pathogens against antibiotics has prompted us to intensify our search for novel lead structures from microorganisms and fungi, which can be used as anti-infective drugs.
Laboratory of Transmission Immunology
Transmission of viruses is only possible during a specific time frame after infection: we can call this the “window of transmission”. A major gap in mitigating (e.g., airborne) transmission and closing this window quickly is the lack of understanding of critical immune determinants of efficient transmission. To be able to close the window of transmission through the design of better mitigation strategies, we develop a mechanistic understanding of the spatial and longitudinal interplay between virus tropism, innate and adaptive immune responses, changes in host physiology, and exhalation or shedding of infectious virus in droplets or fluids.

Human in vitro lung models for testing inhaled drugs
The lung is a highly complex organ made up of over 50 different cell types. In the alveoli, a single layer of cells forms the barrier through which the exchange of oxygen and CO2 between the lungs and the bloodstream takes place. This barrier, also known as the…
A new addition to the CRISPR toolbox: Teaching the gene scissors to detect RNA
Bacteria have developed special defense mechanisms to protect themselves against viruses, which by no means infect only humans. As part of these so-called CRISPR-Cas systems, a CRISPR ribonucleic acid (crRNA), which serves as a “guide RNA,” recognizes regions of a…
Antibiotics of the future?
The collection of myxobacteria at the Helmholtz Centre for Infection Research (HZI) has proven time and again to be a real treasure trove. The soil bacteria, which were initially regarded as not cultivable, have been grown and researched on a large scale since the 1970s…
