alpha-Amylase from the Hyperthermophilic Archaebacterium Pyrococcus furiosus
Description:
In this article, Anfinsen, et al, reported that while trying to study the factors that influenced protein thermostability, or the ability to remain stable at relatively high temperatures, they had cloned a gene from the hyperthermophilic bacterium Pyrococcus furiosus encoded with a highly thermostable alpha-amylase and expressed it in Escherichia Coli. The alpha-amylase expressed in E. Coli exhibited the temperature-dependent activation characteristic of the original enzyme from P. furiosus, but had a higher apparent molecular weight that was attributed to the improper formation of the native quaternary structure.
