Taq DNA polymerase
Posted 21 January 2011 - 03:41 AM
It is well-known that taq DNA polymerase makes errors during PCR, the reason for which proof reading enzymes like Pfu DNA polymerase are preferred. How can the bacteria compensate the errors made by Taq polemerase as compared those harboring proofreading enzymes? Is it that Thermus aquaticus has other proofreading enzymes and that pyrococus species having Pfu doesn't need such enzymes?

Thanks for giving it a thought bob
But when we for instance compare between Thermus aquaticus and Pyrococus furiosus which both are extremophiles, how can such difference be explained?
