Excisionase complex with DNA
Excisionase complex with DNA. Molecular model of three excisionase proteins (bottom, purple, green and blue) bound to a strand of DNA (top, deoxyribonucleic acid). This exisionase protein is called Xis. The proteins have produced a slight curve in the DNA strand, which helps orientate it correctly for further stages in the intasome processes that integrate and excise genetic material. Excisionase is a bacteriophage protein, in this case from the Enterobacteria lambda phage that infects Escherichia coli bacteria

EDITORS COMMENTS
This print showcases the Excisionase complex with DNA, providing a visual representation of the intricate molecular processes involved in genetic integration and excision. The image features a molecular model of three Excisionase proteins, colored in purple, green, and blue at the bottom, bound to a strand of DNA at the top. The main protein highlighted here is Xis, which belongs to the Excisionase family found in bacteriophages such as Enterobacteria lambda phage that infect Escherichia coli bacteria. As depicted in this illustration on a white background, these proteins have caused a slight curve in the DNA strand. This curvature plays an essential role in correctly orienting it for subsequent stages within intasome processes. The double helix structure of deoxyribonucleic acid (DNA) is clearly visible and manipulated by these biomolecules. Through their precise interaction with DNA molecules, Excisionase proteins facilitate genetic material excision and integration. This artwork not only provides insight into the structural aspects but also emphasizes how biochemical manipulation occurs at a microscopic level. It serves as a reminder of how viruses like bacteriophages interact with bacterial hosts like Escherichia coli through intricate protein-DNA interactions. Overall, this visually stunning print from Science Photo Library captures both scientific complexity and artistic beauty while shedding light on crucial biological mechanisms involving genetics and viral infections.
