Credit rating | 10 |
Unit level | Level 3 |
Teaching period(s) | Semester 1 |
Offered by | School of Biological Sciences |

Overview
Macromolecular recognition at the structural level is key to driving biological function. You will study a wide range of examples, from small molecule recognition and drug design, through to recognition of proteins and nucleic acids. You will use molecular graphics software to gain a greater understanding and depth of knowledge in this area.

BIOL31341 Pre-requisite is BIOL21111
Aims
The unit aims to provide an introduction to macromolecular recognition at the structural level, encompassing the widest range of examples, from small molecule recognition and drug design, through to recognition of proteins and nucleic acids, and how this drives biological function. Drug intervention of molecular interactions is a recurring theme and, where appropriate, interactions are set in the broader context of a cellular ‘system’. The unit also aims to invoke greater understanding and depth of knowledge though the use of a molecular graphics interface.
Learning outcomes
Students will be able to:
- describe the molecular basis for recognition of small molecule ligands by proteins, and how this knowledge can be applied to drug discovery
- describe the molecular basis for protein-protein interactions, giving specific examples, plus also relating such interactions to a cellular ‘system’
- appreciate the role of membrane components in the modulation of biological processes, including signal transduction across the membrane, and the functional organisation of membrane proteins
- describe the molecular basis and functional genomics of protein-DNA interaction, differentiate between specific and non-specific interactions, and describe some structural motifs involved
- describe the structural features of protein-RNA interactions, and how they contribute to ribosome assembly and function
- use molecular graphics software in an interactive manner and use it to draw appropriate conclusions concerning macromolecular recognition
- develop organisational and presentational skills to prepare an assessed essay
