Protein engineering on enzymes of the peptide elongation cycle in Sulfolobus solfataricus

The present article is a review of the work done on the elongation factors EF-1 alpha, EF-2 and EF-1 beta isolated from the hyperthermophilic archaeon Sulfolobus solfataricus. The molecular, physical and biochemical propertie s of the intact, truncated, mutant or chimeric forms are described and comp ared.
