Beta-galactosidase, Metabolic Enzyme
A team from Dr. Sriram Subramaniam's lab at NCI's Center for Cancer Research used high-resolution cryo-electron microscopy to create this angstrom resolution electrondensity map of beta-galactosidase. An essential enzyme in the human body, beta-galactosidase is commonly used in molecular biology as a marker to monitor the expression of genes. The map is colored by protein subunit. As of October 2015 it is the highest resolution structure determined by single-particle cryo-EM to date. Beta-galactosidase is an enzyme occurring in certain yeasts and in the intestinal juices of mammals, especially one that catalyzes the hydrolysis of lactose into glucose and galactose.
