Investigating RNA polymerase regulation in the antibiotic-producing Streptomyces bacteria
A Ph.D. studentship (42 months) is available from September 2017 under the supervision of Dr Mark Paget, Department of Biochemistry, School of Life Sciences
The discovery of new antimicrobials is key to meeting the global antimicrobial resistance (AMR) challenge and new genome mining and synthetic biology approaches are leading to a resurgence in the hunt for natural products as leads. Most antibiotics derive from actinobacteria – a diverse group of Gram-positive bacteria that include the Streptomyces genus. Surprisingly, genome sequencing has revealed that the genomes of these bacteria are full of gene clusters that have the potential to produce antibiotics but are not expressed in the laboratory, which prevents the screening of potentially life-saving drugs. This PhD project aims to understand how the transcription machinery – RNA polymerase – is controlled and to develop novel ways of stimulating the expression of these silent pathways. It stems from our research that revealed that RNA polymerase from actinobacteria has unusual general transcription factors not found in other bacteria (Tabib-Salazar et al Nucl Acids Res, 2013; Hubin et al PNAS, 2015) and that certain mutations can stimulate antibiotic production.
Research questions will include: how is the cellular level of RNA polymerase controlled and what are the roles of general transcription factors in remodelling the transcriptome towards antibiotic production? The successful applicant will receive training in microbiology, biochemistry and molecular biology, apply modern genomic techniques such as RNA-seq, and develop their research and transferable skills supported by the Sussex Postgraduate Skills Programme.
