LAC repressor molecule F006 / 9520
LAC repressor. Molecular model of a LAC (lactose) repressor molecule. The LAC repressor inhibits the expression of genes that code for an enzyme which metabolizes lactose in bacteria. It is only present when lactose levels are low. This ensures that the bacteria only produce machinery used for the uptake and breakdown of lactose, when lactose is actually present

EDITORS COMMENTS
This print showcases the intricate structure of the LAC repressor molecule F006/9520. The molecular model, set against a clean white background, highlights the complexity and importance of this protein in regulating gene expression. The LAC repressor plays a crucial role in bacteria by inhibiting the expression of genes responsible for metabolizing lactose. It acts as a safeguard mechanism, ensuring that machinery for lactose uptake and breakdown is only produced when lactose levels are low. This fine-tuned regulation prevents unnecessary energy expenditure by bacteria when lactose is not present. The artwork beautifully captures the alpha helix and beta sheet structures that make up this fascinating molecule's tertiary structure. Its binding capabilities are illustrated through its interaction with DNA strands, emphasizing its role in controlling gene activity. This image holds immense significance in bacteriology research and medicine, shedding light on how organisms adapt to their environment at a molecular level. It provides valuable insights into biochemical processes involved in genetic regulation and offers potential applications in proteomics and genetics studies. With its precise cutouts and attention to detail, this print serves as an invaluable resource for scientists, educators, and healthcare professionals alike who seek to deepen their understanding of bacterial biology and explore new avenues within medical research.
