Metal-binding protein bound to DNA

Metal-binding protein bound to DNA. Molecular model of the bacterial metal-binding protein NikR (bottom) bound to a strand of DNA (top, helical, deoxyribonucleic acid). The NikR protein is involved in the binding and transport of nickel ions. The binding process shown here is known as transcriptional repression. The NikR protein is classed as a ligand-responsive transcription factor. It regulates nickel concentrations in Escherichia coli bacteria

EDITORS COMMENTS
This print showcases the intricate molecular model of a metal-binding protein bound to DNA. The bottom part of the image displays the bacterial metal-binding protein NikR, while the top reveals a helical strand of DNA, known as deoxyribonucleic acid. This particular protein plays a crucial role in binding and transporting nickel ions within Escherichia coli bacteria. The process depicted here is called transcriptional repression, where the NikR protein acts as a ligand-responsive transcription factor. Its primary function involves regulating nickel concentrations within bacterial cells. Against a striking black background, this illustration beautifully captures the structural complexity and interplay between metal ions and genetic material. With its emphasis on biology and genetics, this artwork symbolizes an important aspect of molecular biology research. It highlights how transition metals like nickel can interact with specific proteins to influence cellular processes in organisms such as bacteria. Science Photo Library has masterfully crafted this graphic representation that combines elements from biochemistry, genetics, and proteomics into one visually stunning piece. Through their expertise in capturing scientific concepts through visual media, they have created an engaging portrayal that sparks curiosity about the intricate world of biomolecules and their interactions at a molecular level.
