Making the Bend: DNA Tertiary Structure and Protein-DNA Interactions
نویسندگان
چکیده
DNA structure functions as an overlapping code to the DNA sequence. Rapid progress in understanding the role of DNA structure in gene regulation, DNA damage recognition and genome stability has been made. The three dimensional structure of both proteins and DNA plays a crucial role for their specific interaction, and proteins can recognise the chemical signature of DNA sequence ("base readout") as well as the intrinsic DNA structure ("shape recognition"). These recognition mechanisms do not exist in isolation but, depending on the individual interaction partners, are combined to various extents. Driving force for the interaction between protein and DNA remain the unique thermodynamics of each individual DNA-protein pair. In this review we focus on the structures and conformations adopted by DNA, both influenced by and influencing the specific interaction with the corresponding protein binding partner, as well as their underlying thermodynamics.

SPECTROSCOPIC EVALUATION OF THE INTERACTION OF A TETRAZOLE DERIVATIVE SYNTHESIZED BY SEMI-GREEN METHOD WITH CALF THYMUS DNA AND BOVINE SERUM PROTEIN
Background & Aims: In recent decades, the application of tetrazole structures in various fields of medicine and industry has become very important, because they can cause structural and thus functional changes in the proteins. In this article, the effect of a new tetrazole derivative on calf thymus DNA (Ct-DNA) as well as on bovine serum albumin protein (BSA) in the solution was determined usin...

ABSTRACT In eukaryote cells, DNA is complexed with a series of basic proteins making units of chromatin structure named nucleosomes. In addition, nonhistone proteins with different function are the components of chromatin. Among these proteins, a group with a low mobility on gel electrophoresis have been identified and named LMG. In this study a LMG protein with a molecular weigh of 160 ...
متن کاملProtein Secondary Structure Prediction: a Literature Review with Focus on Machine Learning Approaches
DNA sequence, containing all genetic traits is not a functional entity. Instead, it transfers to protein sequences by transcription and translation processes. This protein sequence takes on a 3D structure later, which is a functional unit and can manage biological interactions using the information encoded in DNA. Every life process one can figure is undertaken by proteins with specific functio...
متن کاملComparative Investigation of R213G Mutation in DNA-Binding Domain of P53 Protein via Molecular Dynamics Simulation
Introduction: P53 is a tumor suppressor protein with numerous missense mutations identified in its gene. These mutations are observed in a vast number of cancers. R213G is one of them which has a role in metastatic lung cancers. In this research, R213G was studied in comparison with the wild type via molecular dynamics simulation. Method: For the three-dimensional structure of the wild-type P53...
