1. Ren, Wenhui. SINGLE MOLECULE FRET STUDY OF.

Degree: MS, Chemistry, 2010, Penn State University

The assembly of bacteriophage T4 leading strand polymerase holoenzyme is accomplished with coordination of multi-proteins. To study the stepwise mechanism of this process, single molecule fluorescence resonance energy transfer (smFRET) technique was used. Clamp loading and unloading of T4 were examined by comparing the FRET signal between holoenzyme with and without its polymerase, and by comparing the FRET signal between the hydrolysable holoenzyme and non-hydrolysable holoenzyme. Results showed that the clamp loading is a multi-step mechanism involving various yet unidentified conformations of clamp•clamp-loader complex. It was suggested that there might be three intermediate states of the holoenzyme. The population of the intermediate species and the rate of assembly of the holoenzyme complex from the DNA are greatly enhanced by the presence of the polymerase.
