DNA can shape itself into many forms to achieve its purposes in life. The crystal structure of the junction between two of its forms provides insight into how DNA might accomplish some of these acrobatics.The B to Z of DNAThe existence of left-handed DNA (or Z-DNA) was reported in 1979, and marked by a Nature cover. This week's cover story is the determination of the crystal structure of the junction between left-handed DNA and ‘normal’, right-handed DNA or B-DNA. Each time a DNA segment turns…

Background: As Yu.P. Blagoi, the memory of who is dedicated to this work, once said: "The molecular structure of DNA — the famous double helix — is stabilized by water molecules and metal ions". The
Bullied no more: when and how DNA shoves proteins around
This work discusses how elastic energy arising from supercoiling and electrostatic energy are harnessed for topology-driven, sequence-specific deformations that can allow DNA to direct its own metabolism.
Genome-Wide Analyses of Recombination Prone Regions Predict Role of DNA Structural Motif in Recombination
Genome-wide computational analyses presented here reveal enrichment of potential G4 (PG4) DNA forming sequences within 25618 human hotspots relative to 9290 coldspots, supporting involvement of G4 DNA in recombination and predicting a functional model that is consistent with duplex-strand separation induced by formation of G 4 motifs in supercoiled DNA and/or when assisted by other cellular factors.

Intrinsic fluorescence of B and Z forms of poly d(G-m5C).poly d(G-m5C), a synthetic double-stranded DNA: spectra and lifetimes by the maximum entropy method.
A study has been made of the fluorescence of poly d(G-m5C).poly d(G-m5C), a synthetic double-stranded DNA, in buffered neutral aqueous solution at room temperature, excited by synchrotron radiation
Light-Directed Dynamic Chirality Inversion in Functional Self-Organized Helical Superstructures.
This Review is expected to provide useful guidelines toward the development of self-organized soft materials with stimuli-directed chirality inversion capability and multifunctional host-guest systems.
The protective role of DOT1L in UV-induced melanomagenesis
It is demonstrated that, in contrast to MLL-rearranged leukemia, DOT1L plays a protective role in ultraviolet radiation (UVR)-induced melanoma development, by facilitating DNA repair through interaction with XPC.
Chromosome Banding and Mechanism of Chromosome Aberrations
The chapter will highlight the karyotypes and its components, karyotype trends, evolution and its role in speciation, banding pattern and techniques, chromosome differentiation and linearization,Banding applications and their uses, detection and analysis of chromosomal aberrations, chromosome and chromatid types of aberration and mechanism of the formation of chromosome aberrATIONS and breaks for kARYotype evolutionary trends.
From 1D zigzag chains to 3D chiral frameworks: synthesis and properties of praseodymium(III) and neodymium(III) coordination polymers
Reaction of H3TDA with PrIII/NdIII salts resulted in two coordination polymers, [Ln(H2O)4(HTDA)(H2TDA)]·H2O (Ln = Pr(1) and Nd(2), H3TDA = 1H-[1,2,3]-triazole-4,5-dicarboxylic acid), crystallizing in
Premutation allele pool in myotonic dystrophy type 2
It is concluded that unstable uninterrupted (CCTG)22-33 alleles represent a premutation allele pool for DM2 full mutations.


Crystal structure of a junction between B-DNA and Z-DNA reveals two extruded bases
The structure of a B–Z junction as revealed by X-ray crystallography at 2.6 Å resolution is described, with the breaking of one base pair at the junction and extruded bases on each side that may be sites for DNA modification.
DNA Structure and Function
This chapter discusses the structure and function of DNA, which is a right handed helix of two individual antiparallel DNA strands that is the source of all intrinsic genetic information.
Modeling DNA deformations.
The energetics of the B-Z transition in DNA.
The theoretical assumption that the free energy of Z-form pairs does not depend on the type of adjacent pairs proved to be in agreement with the experimental data and resulted in a complete set of six energy parameters for the B-Z transition.
Crystal structure of the Zalpha domain of the human editing enzyme ADAR1 bound to left-handed Z-DNA.
The editing enzyme double-stranded RNA adenosine deaminase includes a DNA binding domain, Zalpha, which is specific for left-handed Z- DNA, and the helix-turn-helix motif, frequently used to recognize B-DNA, is used by Zalpha to contact Z-DNA.
Z-DNA: the long road to biological function
The most recent data show that some classes of proteins bound to Z-DNA with high affinity and great specificity participate in the pathology of poxviruses.
Z-DNA-binding proteins can act as potent effectors of gene expression in vivo
The role of Z-DNA-binding proteins in vivo is explored in yeast and it was found that even in the absence of the activation domain there is substantial transcription of the reporter gene if the Z- DNA-binding protein is expressed in the cell.
A role for Z-DNA binding in vaccinia virus pathogenesis
The N-terminal domain of the E3L protein of vaccinia virus has sequence similarity to a family of Z-DNA binding proteins of defined three-dimensional structure and it is necessary for pathogenicity in mice, and may allow the design of a class of antiviral agents.
