Verrucosispora AB18-032 and natural products
One of our main research interests is the marine actinomycete species Verrucosispora AB18-032. This species is responsible for the production of the first-in-class natural product abyssomicin C. Abyssomicin C inhibits the essential folic acid pathway present in bacteria and plants. In collaboration with Prof Sussmuth, we recently published how abyssomicin C is biosynthesized. We have completed the full genome sequence of the abyssomicin producer and are currently using genome mining techniques to identify novel bioactive compounds.
Peptide-PNA conjugates as species-specific antimicrobials
This research is funded by a Nuffield new lecturers award. The aim of the research is to develop peptide-PNA conjugates that can specifically target, and prevent transcription of, specific essential bacterial genes. Research in other labs has shown that it is possible to use such conjugates to target bacterial genes. However, the novelty of this research lies in the combination of using essential genes with species-specific sequences. Thus, peptide-PNA conjugates could be used to select target species without providing selection pressure for resistance in non-target organisms. We have recently proven that it is indeed possible to target species for bactericide in a species-specific manner that is not achievable using conventional antibiotics (see publications).
Antisense-based antimicrobial screens
This research is funded by a BBSRC DTG grant. The aim of the study is to develop and validate screens for antibacterial compounds. Induction of antisense RNA reduces the expression of its cognate protein and sensitises the strain to inhibition of that protein. This is of particular value in natural products research where effective antimicrobial compounds may be present in extracts but in amounts below the minimum inhibitory concentration for a wild-type screen. We have recently used this methodology to identify plant-derived inhibitors of the bacterial cell division protein FtsZ . We have also used this methodology to identify the stringency of requirement for essential genes in E. coli that will aid in prioritising targets for drug discovery. Current research aims at validating the screens by correlating protein abundance with mRNA abundance during antisense expressing and using microarrays to demonstrate the specificity of the gene silencing. As such we are developing and validating novel methods that will enable absolute quantification of the amount of specific protein per cell in E. coli.
