Multi-scale measurements in biophysical systems

Project dates: 1 Apr 2010 - 31 Dec 2014

The metrological foundations underlying biomolecular structure and function are sparse and fail to keep pace with the demands of molecular medicine and the attempts to provide solutions to global health challenges such as viral epidemics, anti-microbial resistance and metastatic cancers.

Validated measurements and standardisation techniques are needed to enable any sustainable progress in this area and to advance our understanding of structure-activity links at the molecular and supramolecular levels, thereby providing key principles for rational drug design and molecular diagnostics.

This project aims to establish a comprehensive metrology infrastructure that will extend our understanding of key relationships between biomolecular structure, dynamics and function. This will be achieved by providing definitive structural measurements of polypeptides and their properties in native molecular and cellular environments. A sufficiently extensive international effort within the project will transform into a leading metrology centre generating major downstream economic and healthcare impacts. The scientific and technological methodologies developed will be used to validate generic rules, first design principles, to enable polypeptide sequence-to-function prediction.

This project addresses the most pressing measurement challenges pertaining to:

  • incompleteness in detail of biomolecular structure-function relationships; and
  • lack of biomolecular measurands, established reference methodologies and reference materials, and particularly those related to protein folding in native environments.

New solutions to these challenges will provide a measurement-based rationale for efficient sequence-to-function prediction approaches.
