What is the molecular basis of the stability of the bacterium Thermus aquaticus and the enzyme Taq Pol it produces ?
I have tried googling this but did not get a good answer.
Here is an article from Razvi and Scholtz that help you understand the thermostability found in thermophilic proteins. They compared protein stability of thermophilic proteins and their homologous versions in mesophilic bacteria (i.e., bacteria that grow in more normal temperature ranges), and compiled these proteins into a database. Their method was to make estimates of protein stability curves for each of these proteins through a model of free energy based on the known physical parameters of these proteins. From the article:
This is achieved through mutation of just the linear sequence of the protein. Fundamentally,
Also, everything I have seen about the genus thermus places them as Gram negative bacteria.
