Abstract

We wish to extend the time domain accessible for spectroscopic studies of protein folding from milliseconds to the nanosecond regime. We have developed an ultrafast temperature jump apparatus and a mechanism for probing the subsequent folding using fluorescence. We wish to capitalise on this work by adding an experienced biophysicist to the project team and by replacing extremely unreliable second hand laser equipment. We shall test the system using apomyoglobin as a model protein and go on to study, with unprecedented time resolution, the refolding of the histidine containing protein HPr and modified human growth hormone which is of interest to our industrial partners, Duramed Europe Ltd. This project will also form the basis of a proposal for a time resolved CD or Raman spectroscopic probe of secondary structure formation in the near future.
