Gene transcription is a process by which information encoded in DNA is transcribed into RNA. Eva Nogales, Berkeley Lab View Media

Katanin protein regulates anaphase

2594

The microtubule severing protein, katanin, localizes to chromosomes and regulates anaphase A in mitosis. David Sharp, Albert Einstein College of Medicine View Media

Self-organizing proteins

2771

Under the microscope, an E. coli cell lights up like a fireball. Each bright dot marks a surface protein that tells the bacteria to move toward or away from nearby food and toxins. View Media

dUTP pyrophosphatase from M. tuberculosis

2381

Model of an enzyme, dUTP pyrophosphatase, from Mycobacterium tuberculosis. Drugs targeted to this enzyme might inhibit the replication of the bacterium that causes most cases of tuberculosis. Mycobacterium Tuberculosis Center, PSI View Media

Cryo-electron tomography of a Caulobacter bacterium

6569

3D image of Caulobacter bacterium with various components highlighted: cell membranes (red and blue), protein shell (green), protein factories known as ribosomes (yellow), and storage granules Peter Dahlberg, Stanford University. View Media

Sortase b from B. anthracis

2386

Structure of sortase b from the bacterium B. anthracis, which causes anthrax. Sortase b is an enzyme used to rob red blood cells of iron, which the bacteria need to survive. Midwest Center for Structural Genomics, PSI View Media

PanB from M. tuberculosis (1)

2380

Model of an enzyme, PanB, from Mycobacterium tuberculosis, the bacterium that causes most cases of tuberculosis. This enzyme is an attractive drug target. Mycobacterium Tuberculosis Center, PSI View Media

Seeing signaling protein activation in cells 02
