Dynamin Fission

3448

Time lapse series shows short dynamin assemblies (not visible) constricting a lipid tube to make a "beads on a string" appearance, then cutting off one of the beads i.e., catalyzing membrane fission). Ramachandran, Pucadyil et al. , The Scripps Research Institute View Media

Nuclear Lamina

6572

The 3D single-molecule super-resolution reconstruction of the entire nuclear lamina in a HeLa cell was acquired using the TILT3D platform. Anna-Karin Gustavsson, Ph.D. View Media

CCP enzyme

6762

The enzyme CCP is found in the mitochondria of baker’s yeast. Scientists study the chemical reactions that CCP triggers, which involve a water molecule, iron, and oxygen. Protein Data Bank. View Media

Movie of the 19S proteasome subunit processing a protein substrate

3764

The proteasome is a critical multiprotein complex in the cell that breaks down and recycles proteins that have become damaged or are no longer needed. Andreas Martin, HHMI View Media

Structure of heme, top view

Molecular model of the struture of heme. Heme is a small, flat molecule with an iron ion (dark red) at its center. Rachel Kramer Green, RCSB Protein Data Bank View Media

ARTS triggers apoptosis

2432

Cell showing overproduction of the ARTS protein (red). ARTS triggers apoptosis, as shown by the activation of caspase-3 (green) a key tool in the cell's destruction. The nucleus is shown in blue. Hermann Steller, Rockefeller University View Media

Bovine trypsin

A Growing Bacterial Biofilm

5825

A growing Vibrio cholerae (cholera) biofilm. Cholera bacteria form colonies called biofilms that enable them to resist antibiotic therapy within the body and other challenges to their growth.

Histone deacetylases

7001

The human genome contains much of the information needed for every cell in the body to function. However, different types of cells often need different types of information. Amy Wu and Christine Zardecki, RCSB Protein Data Bank. View Media

Zebrafish embryo

6897

A zebrafish embryo showing its natural colors. Zebrafish have see-through eggs and embryos, making them ideal research organisms for studying the earliest stages of development. Michael Shribak, Marine Biological Laboratory/University of Chicago. View Media

Early life of a protein

2740

This illustration represents the early life of a protein—specifically, apomyoglobin—as it is synthesized by a ribosome and emerges from the ribosomal tunnel, which contains the newly formed protein's Silvia Cavagnero, University of Wisconsin, Madison View Media

Cryo-electron microscopy of the dengue virus showing protective membrane and membrane proteins
