• PubMed Abstract: 
  

The hyperthermophile Pyrococcus furiosus is one of the most thermostable organisms known, with an optimum growth temperature of 100 degrees C. The proteins from this organism display extreme thermostability. We have undertaken the structure determination of glutamate dehydrogenase from P. furiosus in order to gain further insights into the relationship between molecular structure and thermal stability.
