Scientists have for the first time looked deep into the protein structure that may determine our vision - and discovered that ...

Researchers used space-grown protein crystals to determine the structure of a helix-loop-helix (HLH) peptide (one with a double helix and connecting loop) in a complex with vascular endothelial ...

to argue that DNA actually takes the form of a double helix, a ladder-like structure that is twisted along its entire length (Figure 6). Franklin, Watson, and Crick all published articles ...

However, the structure of the winged-helix protein, hRFX1, bound to DNA reported in a recent issue of Nature 1 has revealed a striking counter example to this rule. Figure 1: Structure of two ...

Scientists still needed to figure out this molecule's structure to be sure, and to understand how it worked. In 1948, Linus Pauling discovered that many proteins take the shape of an alpha helix ...

represent the genetic code that instructs cells how to make proteins. Understanding this structure is essential for studying heredity and genetic information. (Image: National Human Genome Research ...

Collagens are the most prevalent proteins in the human ... collagens consist of a rope-like structure of three interwoven strands known as a triple helix. Collagen self-organization begins at ...
