Insights Into The Proteasome - A Fascinating Macromolecular Machine For Protein Degradation
... exclusion mechanism was visualized by electron microscopy with a gold labeled insulin b -chain caught in transit; the bulky gold label prevents the insulin chain from passing the constriction. The enzymatic mechanism of the proteasome has been a mystery until crystal structure analysis a...Hultgren Receives Prestigious Eli Lilly Award
