Research Assistant in Biological Chemistry
Cardiff School of Chemistry
Cardiff University

We seek to recruit an enthusiastic, highly motivated scientist with proven intellectual and technical abilities to work on a Biotechnology and Biological Science Research Council (BBSRC)-funded biological chemistry project.

The overall objective of this research project is to characterise the protein electrostatic properties of Dihydrofolate reductase (DHFR) via vibrational Stark effect measurements via incorporation of cyanide probes into a protein to reveal subtle electrostatic changes within the protein microenvironment (Stark effect).

Applicants must hold a 2:1 or 1st Class Honours degree (or equivalent) in Biological/Organic Chemistry or Biochemistry especially relative to Synthetic Biology, or equivalent industrial experience.

Additional Information

Project Description

This project aims to investigate the nature of protein electrostatics in Dihydrofolate reductase (DHFR) catalysis. The underlying role of protein electrostatics in enzyme catalysis needs to be deciphered in order to build a precise model for DHFR catalysis. We hypothesise that enzymes need to sample an electrostatically preorganised configuration to find the best configuration for the reaction to occur. Accordingly, both protein dynamics and electrostatics need to be characterised. Here we will characterise the protein electrostatic properties of DHFR via vibrational Stark effect measurements. Incorporating a cyanide probe into a protein reveals a unique infrared (IR) signal, the changes of which caused by amino acid replacement and/or ligand binding can reveal subtle electrostatic changes within a protein microenvironment, hence vibration Stark effect. Natural aromatic residues in the active site will be replaced by commercially available unnatural amino acid such as cyanylated phenylalanine using the aminoacyl transfer ribonucleic acid (tRNA) synthetase variant made available in our laboratory from previous work. Ligand binding will lead to a strong different in the measured vibration Stark effects, The IR spectroscopic measurement will be combined with site-directed mutagenesis studies to investigate the roles of catalytically important residue in catalysis. To confirm our experimental results, vibrational Stark effects will also be performed computationally with collaborators.
