Structural characterisation of the complete cycle of sliding clamp loading in Escherichia coli

Z.-Q. Xu, S. Jergic, A. T. Y. Lo, A. C. Pradhan, S. H. J. Brown, J. C. Bouwer, H. Ghodke, P. J. Lewis, G. Tolun, A. J. Oakley, N. E. Dixon

This study presents six high-resolution structures of the E. coli clamp loader complex (CLC) during the clamp loading process, revealing the molecular mechanism of clamp opening and DNA binding.

Single-molecule visualization of stalled replication-fork rescue by the Escherichia coli Rep helicase

K. S. Whinn, Z.-Q. Xu, S. Jergic, N. Sharma, L. M. Spenkelink, N. E. Dixon, A. M. van Oijen, H. Ghodke

This study visualizes how the Escherichia coli Rep helicase rescues stalled replication forks by removing roadblocks, showing replication restart is the rate-limiting step.

Mechanism of transcription modulation by the transcription-repair coupling factor

B. P. Paudel, Z.-Q. Xu, S. Jergic, A. J. Oakley, N. Sharma, S. H. Brown, J. C. Bouwer, P. Lewis, N. E. Dixon, A. M. van Oijen, H. Ghodke

This study investigates how the bacterial TRCF Mfd modulates transcription by converting elongation complexes into catalytically poised states and then irreversibly terminating transcription through ATP hydrolysis.

Recycling of single-stranded DNA-binding protein by the bacterial replisome.

L. M. Spenkelink, J. S. Lewis, S. Jergic, Z.-Q. Xu, A. Robinson, N. E. Dixon, A. M. van Oijen

This study visualizes how the E. coli replisome recruits and recycles single-stranded DNA-binding protein using two mechanisms, showing their physiological relevance.

A Primase-Induced Conformational Switch Controls the Stability of the Bacterial Replisome

E. Monachino, S. Jergic, J. S. Lewis, Z.-Q. Xu, A. T. Y. Lo, V. L. O Shea, J. M. Berger, N. E. Dixon, A. M. van Oijen

This study identifies a primase-induced conformational switch that enhances the stability of the bacterial replisome by strengthening the interaction between the polymerase holoenzyme and the replicative helicase.
