Description
Beta-galactosidase enzyme. Illustration of a density map of the enzyme beta-galactosidase, determined by cryo-electron microscopy to a resolution of 2.2 angstroms. 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 model is coloured by protein subunit. The illustration includes an electron beam striking a specimen grid (upper left), while the background shows the atomic contours of amino acids in the structure. This model was produced using high-resolution cryo-electron microscopy at Sriram Subramaniam's laboratory at the National Cancer Institute's Center for Cancer Research in the USA. Image published in 2015.
