Interchangeable modules in bacterial thiol-disulfide exchange pathways

BiBTeXThiol-disulfide oxidoreductases (TDORs) catalyze thiol-disulfide exchange reactions that are crucial for protein activity and stability. Specifically, they can function as thiol oxidases, disulfide reductases or disulfide isomerases. The generally established view is that particular TDORs act unidirectionally within a fixed cascade of specific, sequentially arranged reactions. However, recent studies on both Gram-negative and Gram-positive bacteria imply that this view needs to be expanded, at least for thiol-disulfide exchanges in proteins that are exported from the cytoplasm. Here, we present our opinion that various TDORs can function as interchangeable modules in different thiol-disulfide exchange pathways. Such TDOR modules, thus, fulfil important functions in generating the diversity in activity and specificity that is needed in productive extracytoplasmic thiol-disulfide exchange.

The main area of my expertise concerns protein sorting and secretion in Gram-positive bacteria, such as Bacillus subtilis and Staphylococcus aureus.
The Gram-positive bacterium B. subtilis is well known for its high capacity to secrete proteins into the extracellular milieu, which has led to its exploitation as a "cell factory" for secreted proteins. Nevertheless, the secretion of heterologous proteins of pharmaceutical importance is frequently inefficient. This applied problem has been a major ...

By training I am a molecular microbiologist with a particular interest in bacterial stress adaptation reactions. Since the early 90ies we have used functional genomics technologies, particularly proteomics, to investigate the response of Bacillus subtilis to environmental challenges. I am currently Head of the Functional Genomics Department of the Interfaculty Institute of Genetics and Functional Genomics at the Ernst-Moritz-Arndt-University Greifswald. Within the Department we are applying ...
SysMO is a European transnational funding and research initiative on "Systems Biology of Microorganisms".
The goal pursued by SysMO was to record and describe the dynamic molecular processes going on in unicellular microorganisms in a comprehensive way and to present these processes in the form of computerized mathematical models.
Systems biology will raise biomedical and biotechnological research to a new quality level and contribute markedly to progress in understanding. Pooling European research ...
