A Mass Spectrometer for Structural Biology and Top-down Protein Identification
Lead Research Organisation:
University of Birmingham
Department Name: Sch of Biosciences
Abstract
Proteins are intricate and extensively modified molecules that engage in the formation of loosely-bound complexes with themselves and other biomolecules. Functioning as biological machines, proteins orchestrate the vital processes essential for life, with their roles intricately tied to both their composition and overall structure. Mass spectrometry is an analytical technique which enables us to dive into the workings of proteins, offering a deeper understanding of their functionalities.
This proposal will install the most advanced mass spectrometer for structural biology at the University of Birmingham. This state-of-the-art instrument has the capability to unravel the characteristics of newly identified proteins, shedding light on their coordinated movements with partnering molecules. Equipped with a high mass quadrupole, the mass spectrometer boasts the ability to analyse a diverse variety of large proteins and protein complexes in real time. Crucially, this quadrupole enables low-abundant yet critical proteins, whose misregulation can lead to significant alterations in cellular function, to be isolated in-turn and picked out for analysis from within complex mixtures of hundreds of proteins. In addition, the mass spectrometer will be equipped with a variety of fragmentation techniques that will enable each protein to be characterised with certainty, adding a high level of precision for accurate identification and protein function assignment.
By uniting a broad range of researchers from the University of Birmingham and the Midlands region (University of Warwick, University of Leicester) whose research interests span diverse disciplines, the proposal will apply this state-of-the-art technology to unlock our capabilities to resolve key challenges within key strategic priorities that have been outlined by the BBSRC; understanding the rules of life, transformative technologies, bioscience for sustainable agriculture and food, and biosciences for an integrated understanding of health.
