The stability of Taq DNA polymerase results from a reduced entropic folding penalty; identification of other thermophilic proteins with similar folding thermodynamics.

The thermal stability of Taq DNA polymerase known, and is the basis for use in PCR. A comparison of the thermodynamic characterization of a large fragment of Taq domain (Klentaq) and E. coli (Klenow) of DNA polymerase has done by getting the Gibbs-Helmholtz stability curve full folding free energy (AG) versus temperature. This analysis provides temperature dependencies folding enthalpy and entropy (ΔH and ΔS), and heat capacity (ΔCp) fold.

If increased or enhanced non-covalent bonding in the original state is responsible for increasing the thermal stabilization of proteins, such as frequently asked questions, then folding enthalpy enhanced benefit should, in general, observed for thermophilic proteins. However, for Klenow-Klentaq homologous pairs, folding enthalpy (ΔHfold) of Klentaq far less profitable than Klenow at all temperatures. Instead, it was found that the free energy of folding extreme Klentaq (ΔGfold) comes from the entropic penalty significantly reduces the fold (ΔSfold). In addition, the heat capacity change at a similar fold for Klenow and Klentaq.

Along with this new data, the extended analysis of comparable thermodynamic data is available for 17 pairs of mesophilic-thermophilic proteins other (where applicable thermodynamics enough data available) show the same pattern in seven out of 18 total system. When analyzed with this approach, which is better known as “reduced ΔCp mechanism” for protein thermal stabilization (observed in six different 18 systems) often manifests as a shift from stabilization temperature dependent enthalpy driven model entropic-penalty reduction.

Taq DNA polymerase mutant with improved ability elongation as reagents useful for genetic engineering.

DNA polymerase is widely used for manipulating DNA in vitro, including DNA cloning, sequencing, DNA labeling, mutagenesis, and other experiments. thermostable DNA polymerase is very useful and can be quite worthwhile after the development of PCR technology. A DNA polymerases from Thermus aquaticus (Taq polymerase) is the most well-known DNA polymerase as PCR enzyme, and has been widely used around the world.

In this study, the gene fragment of family A DNA polymerase was amplified by PCR from the DNA of microorganisms in environmental soil samples, using a set of primers for two conserved regions. The corresponding region of the pol gene for Taq polymerase gene fragment was replaced with reinforced, and a variety of chimeric DNA polymerases prepared. Based on these properties chimeric enzymes and their sequence, two residues, E742 and A743, in the Taq polymerase was found to be important for the ability of elongation.

Taq polymerase with mutations in the 742 and 743 actually showed a higher affinity DNA and primer extension capabilities faster. These factors also affect the performance of PCR on DNA polymerase, and the PCR yield improvement was observed with Taq polymerase mutants.
coumarin derivatives
were prepared using a natural product isolated from a plant belonging to the genus Pterocaulon (Asteraceae) and commercial drugs.
