About the Project
Many of antimicrobials are structurally complex organic molecules, which are often chemically synthesized from fossil derived feedstock, the process of which requires energy intensive processing and is considered by many as non-sustainable for the future. Currently, it is the strategic plan for most of the governments in the world that encourages their own countries to become a bio-based economy and to establish a modern system that is clean, low-carbon and efficient in the future. Industrial biotechnology (IB) uses biological resources for producing and processing materials and chemicals as a way of helping to reduce dependency on fossil fuels. This includes the application of newly discovered enzymes to new applications in the bioscience industries. These novel enzymes could provide a new and "clean" means of chemical synthesis in the pharmaceutical and chemical industry. IB as a means of green and sustainable chemistry is the growing research and many governments are investing significant resources and funding in bio-based chemicals and renewable energy, given environmental issues plus foods and energy.
This project is designed to maximise the chance of harnessing a group of previously underexploited antimicrobial natural products and their biosynthetic enzymes to generate antimicrobial compound libraries for structure-activity relationship studies.
Research objectives: 1. Chemical synthesis of a range of thioesters or small peptidyl molecules. 2. Explore the catalytic capacities of novel enzymes using the synthetic molecules; 3. Identification of new biocatalysts with the aim of finding enzymes with enhanced kinetics and substrate flexibility; 4. Development of novel compound libraries for bioactivity screening.
Candidates should have (or expect to achieve) a UK honours degree at 2.1 or above (or equivalent) in Organic chemistry, microbiology or biochemistry or bioorganic chemistry.
This is a cross-disciplinary project involving elements of organic chemistry, molecular biology and protein chemistry. In this project, you will gain experience in chemical synthesis of small molecules, cloning genes for heterologous expression, as well as using the purified enzymes to carry out biotransformation reactions. You will learn chemical characterization by LC-MS and NMR analyses. You will gain experience in organic chemistry, microbiology, molecular biology as well as protein chemistry.
