 Artistic illustration of density map of the enzyme beta-galactosidase (beta-gal) determined by cryo-electron microscopy at 2.2 angstrom resolution. An essential enzyme in the human body, beta-gal is commonly used in molecular biology as a reporter marker to monitor gene expression. The foreground shows the overall shape of the molecule (right) and an electron beam striking a specimen grid (left), while the background shows images of single molecules (upper left) and the atomic contours of amino acids in the structure (lower right). | |

 2.2 angstrom resolution electron density map of beta-galactosidase (beta-gal) as determined by high-resolution cryo-electron microscopy (cryo-EM). An essential enzyme in the human body, beta-gal is commonly used in molecular biology as a reporter marker to monitor gene expression. 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. | |
