Helix untwisting and bubble formation in circular DNA.
The base pair fluctuations and helix untwisting are examined for a circular molecule. A realistic mesoscopic model including twisting degrees of freedom and bending of the molecular axis is proposed. The computational method, based on path integral techniques, simulates a distribution of topoisomers with various twist numbers and finds the energetically most favorable molecular conformation as ...
متن کاملHelix-coil Transition in Closed Circular DNA
A simplified model for the closed circular DNA (ccDNA) is proposed to describe some specific features of the helix-coil transition in such molecule. The Hamiltonian of ccDNA is related to the one introduced earlier for the linear DNA. The basic assumption is that the reduced energy of the hydrogen bond is not constant through the transition process but depends effectively on the fraction of alr...

متن کاملDNA recognition and superstructure formation by helix-turn-helix proteins.
The way helix-turn-helix proteins recognize DNA is analysed by comparing their sequences, structures, and binding specificities. Individual recognition helices in these proteins bind to four DNA base pairs with the same geometry. However, pairs of recognition helices in the protein dimers can have different separations and orientations. These differences are used for discriminating between DNAs...
متن کاملUntwisting of the DNA helix stimulates the endonuclease activity of Bacillus subtilis Nth at AP sites
Bacterial nucleoid associated proteins play a variety of roles in genome maintenance and dynamics. Their involvement in genome packaging, DNA replication and transcription are well documented but it is still unclear whether they play any specific roles in genome repair. We discovered that untwisting of the DNA double helix by bacterial non-specific DNA binding proteins stimulates the activity o...
