Proteins are the end products of the decoding process that starts with the information in cellular DNA. As workhorses of the cell, proteins compose structural and motor elements in the cell, and ...

This article was originally published with the title “ The Three-Dimensional Structure of a Protein Molecule ” in Scientific American Magazine Vol. 205 No. 6 (December 1961), p. 96 doi:10.1038 ...

Each gene contains a coded instruction for making a single protein. The chemical code in which the information is written is stunningly simple ... twisted double strand structure -- the famed ...

In living organisms, protein molecules with different chemical structures called proteoforms ... of proteoforms using the inexpensive and simple SDS- PAGE system. Sample fractionation using ...

“Not just the spatial structure of the protein but how it changes over time, and that seemed like a perfect match for sound as sound doesn’t even exist without time.” Usually, scientists visualize ...

Each cell in your body relies on precise communication with other cells to function properly. At the center of this process ...

The result is a three-dimensional Fourier, or electron-density, map of the unit cell, which for the first time reveals the general nature of the tertiary structure of a protein molecule.

The sequence of amino acids in the chain determines how the chain will fold up to make the protein, so different proteins have different three-dimensional shapes. The three-dimensional shape of a ...
