Core modules:

Biostructures, Energetics and Synthesis

This module aims to refresh students' understanding of the structures and functions of proteins and how free energy is made available (transduced) from reduced organic carbon compounds (catabolism) to generate ATP and NADPH for biosynthetic metabolism (anabolism). We begin by taking another look at key catabolic pathways in the cell including glycolysis, the Krebs cycle and mitochondrial electron transfer; before considering fatty acid β-oxidation and the pentose phosphate pathway.  We then explore how amino acids and nucleotides, the building blocks of life, are synthesised. This leads on to a study of the nature of biological membranes and the main functions of membranes in cells, including the transduction of energy, nerve transmission and signalling. We then focus on the structure and function of membrane proteins, highlighting their key role in transport of proteins, small molecules and ions across biological membranes. Finally, we come full circle highlighting how solar energy entering the biosphere is harvested by chlorophyll pigments and transferred to specialised reaction centres to initiate photosynthetic electron transfer. We show how photosynthesis converts solar energy into ATP and NADPH, utilising the same redox chemistry and chemiosmotic principles that underlie respiration, and then uses these metabolites to power the fixation of CO2 into reduced organic carbon compounds.

Biochemistry 2

This module provides an advanced treatment of the biochemical topics introduced in earlier modules, to provide a deep understanding of the underlying chemical principles and molecular interactions governing life in cells. The module begins with a review of the chemical transformations and molecular interactions governing enzyme function. We then study a number of enzyme examples to illustrate common themes arising in enzyme specificity, types of reaction mechanisms and the relationship between protein structure and function. This leads on to study practical methods to experimentally measure enzyme activity. We then take a detailed look at the fundamentals of enzyme and ligand binding kinetics underlying unimolecular and bimolecular irreversible and reversible reactions. We then turn our focus to small molecule drug development, showing how the principles learned earlier in the module can be applied to develop protein or enzyme inhibitors for therapeutic use. The final part of the module develops an understanding of the ways in which kinetic parameters can be used to study reaction mechanisms and how inhibitors and mutants can modulate the activity of enzymes. We also study aspects of protein and enzyme function in practical classes.

Human genomics, proteomics and genome biology

A top-down approach to biology, simultaneously investigating the structure and function of the entire genome and its products, both contrasts with and complements the traditional gene-by-gene approach, allowing us a birds-eye view. In this module, we cover genome-wide approaches to studying the genetic causes and diagnosis of complex and polygenetic human disease. We then discuss how methods such as RNA-seq, ChIP-seq and 4C can be used to investigate the genome-wide transcriptional profile, the chromatin landscape and the three-dimensional structure of the genome. Finally we describe the use of technologies such as mass spectrometry to investigate the complete proteome of a cell. The module builds on the material from the level 2 module Genes, Genomes and Chromosomes, to illustrate how cutting-edge genomic and proteomic methods can be used to address fundamental biological questions.

10 credits

Membrane Protein Structure and Function

The aim of this module is to impart a thorough understanding of the structure and function of membrane proteins. A major theme is the structural basis of energy transduction in membranes. Membrane protein complexes mediate the transfer of excitation energy, electrons and protons upon which all life depends. They also control the entry and exit of proteins, ions, nutrients, drugs and antibiotics from cells and the transfer of signals across membranes. We will examine membrane proteins involved in energy harvesting such as respiration and photosynthesis. The principles underlying the efficiency of energy transduction and redox chemistry taking place in these complexes will be covered. We will look at how harvested energy is coupled to movement of molecules ions and signals across membranes. The role of structure in determining specificity and directionality in vital transport process and signalling will be emphasised.

10 credits

Genome Stability and Genetic Change

The module examines in detail the mechanisms that maintain genome integrity and generate genetic variation, both of which are essential to eukaryotic life. The lectures illustrate how the prevention and creation of changes in DNA make use of the same biochemical machinery. The main emphasis is on eukaryotes; reference is made to prokaryotes mainly as an aid to understanding the importance of conserved processes. Mechanisms studied in detail include single-strand break repair, protein-linked DNA break repair, homologous and non-homologous recombination, avoidance of replication errors, mismatch repair, excision repair and mutagenesis. Throughout the module experimental detail is included to illustrate how conclusions on gene function and interactions have been determined.

10 credits

Bacterial Pathogenicity

Infectious diseases account for the majority of deaths worldwide. This will continue to be the case until we have a greater understanding of the mechanisms of microbial pathogenesis. This course builds on the principles introduced in level 2 microbiology and begins by showing how molecular genetic approaches are being used to unravel the complexities of microbial virulence. Following an introduction to the regulation of virulence genes, the pathogenic mechanisms of selected bacterial pathogens are explored in detail, demonstrating the involvement of multiple virulence determinants and their genetic regulation in the disease process. Mechanisms by which toxins deregulate or kill host cells will be explored. Virulence mechanisms that represent common themes in bacterial pathogenesis will be highlighted. The appearance of antibiotic resistant strains and strategies adopted to tackle this problem will also be considered.

10 credits

The Microbiology of Extreme Environments

The overall aim of this module is to provide a detailed account of how diverse microorganisms survive in extreme environments on Earth. The first part of the course examines a range of extreme environments including salt lakes, hot springs, polar regions, mining areas, soda lakes, deserts, hydrothermal vents and sea ice and explains the metabolic processes of the diverse microbes that inhabit them to grow optimally under these extreme conditions. The growing industrial applications of extremophilic microorganisms will also be covered. The second part of the course looks at how proteins are adapted to remain stable and active under extreme conditions, since proteins readily denature under moderate heat, increased levels of salinity or changes in pH.

A student may take up to 20 credits from any available Level 3 Modules from the School of Biosciences.

Core modules:

Advanced Literature Review: Retrieval and Evaluation of Scientific Information

Students will undertake an in depth survey of the scientific literature relevant to the project. This will involve primarily private study by the student under the direction of the project supervisor, who will meet with the student at regular intervals to ensure satisfactory progress. 

This module is designed to develop the student's ability to read and understand the scientific literature relating to their own research area and also enable them to integrate their own work into the wider scientific field. Students will develop and present a comprehensive understanding of the literature, including the methodological approaches and techniques relevant to their Research Project. This will involve a critical analysis of hypotheses in the field and of the quality of the evidence used to support them. Where controversies exist, the dissertation should indicate which side has the stronger case. The review should include a quantitative analysis of the available evidence related to the scientific question being addressed (e.g. meta-analysis or systematic review of the literature relevant to key concepts). The review should identify gaps in our current knowledge and understanding and make suggestions for the future development of the field, which could include a research proposal outline of the project that they are planning to undertake in the related Research Project module. 

This module will be assessed on the basis of a written report.

20 credits
