WebAn elevated Epot level was detected starting from -2185.69 kcal/mol for the ground state to -2051.68 kcal/mol for the activated state. This mechanism might explain how a BLUF domain interacts with the polymerase or activate it. Similarly, this helps to clarify how a BLUF domain stops or activates the T4 polynucleotide kinase. WebThe “kinase” reaction uses T4 polynucleotide kinase (T4 kinase) to transfer labeled phosphate to the 5′ end of the DNA molecule ( 6) Fig. 1B. This method is ideal for labeling oligonucleotides, which are normally synthesized without a 5′ phosphate.
