	DNA Paper Model Atomic structures reveal how the iconic double helix encodes genomic information
	Green and Red Fluorescent Proteins Paper Model A tiny fluorescent protein from jellyfish has revolutionized cell biology
	G Protein-Coupled Receptor (GPCR) Paper Model GPCRs are a large family of membrane-embedded receptors, with structural features that have been preserved through the course of evolution. This model represents the shared structural features of all GPCRs. With the extracellular N-terminus, the protein chain folds to form a bundle of seven transmembrane alpha helices connected by 3 intracellular and 3 extracellular loops with the C-terminus reaching inside the cell.

	Celebrating 50 Years of the Protein Data Bank Archive Video In 1971, the structural biology community established the single worldwide archive for macromolecular structure data–the Protein Data Bank (PDB). From its inception, the PDB has embraced a culture of open access, leading to its widespread use by the research community. PDB data are used by hundreds of data resources and millions of users exploring fundamental biology, energy, and biomedicine. This video looks at the history and the milestones that shaped the PDB into the leading resource for research and education it is today.

Geis Digital Archive (5)

	Myoglobin Geis highlights the hundreds of chemical bonds in the lattice of myoglobin.
	Ribonuclease S Geis illustrates the structure of the ribonuclease S that highlights the dinucleotide RNA substrate in red and the four disulfide bonds in yellow.
	Hemoglobin Geis illustrates the hemoglobin molecule as four symmetrically arranged myoglobins. Since it is responsible to the transport of oxygen, it can change from an oxygen-binding configuration to an oxygen-releasing configuration in response to the demand for oxygen.
	DNA Geis illustrates a double helix in his depiction of DNA. He portrays the helices with a soft ribbon structure. The white "box-like" structures represent a base pair in the DNA strand.
	B-DNA Geis illustrates B-DNA in blue looking from above, through the double helix. The two bases on top are highlighted in white to distinguish one individual section of the layered scene.
