Project Description

Tetrapyrroles are often referred to as the pigments of life as they are required for a number of vital cellular processes, including respiration (haems), photosynthesis (chlorophylls), amino acid biosynthesis (vitamin B12), sulphur and nitrogen assimilation (sirohaem) and methanogenesis (cofactor F430). These pigments are made on a huge global scale by a system of branched pathways and it is important to understand how organisms control this biosynthetic network, and how they balance levels of each pigment in the cell.

Purple phototrophic bacteria are some of the most metabolically diverse organisms on the planet and are excellent model organisms for studying tetrapyrrole biosynthesis. During photosynthetic growth these bacteria must simultaneously produce haem, sirohaem, bacteriochlorophyll and vitamin B1 and coordinate metabolic flux to each of the pathways. This PhD project will investigate the regulatory and biosynthetic processes that allow these versatile microorganisms to manage tetrapyrrole synthesis to meet their changing biochemical needs.

The successful candidate will receive training in a range of techniques including bioinformatics, molecular genetics, recombinant protein purification, biochemical analysis, enzymology, spectroscopy, structural biology and mass spectrometry. The student will be based in the collaborative, multidisciplinary molecular photosynthesis research group in the Department of Molecular Biology and Biotechnology and will have access to the world-class facilities at the University of Sheffield.
