Proteins are the basic building blocks of life. They play a critical role in cell function and structure and are involved in transport, communication and metabolism in the body. While just 20 amino ...

Scientists demonstrate the influence of nanoparticles and surrounding ions on the formation of beta-sheet structure in amyloid beta proteins. Protein function and activity is determined by both their ...

All proteins are made of basic secondary structure units, either α-helix or β-sheets, determined by hydrogen bonding between the amino acids within a peptide chain. On a larger scale, structures are ...

Proceedings of the National Academy of Sciences of the United States of America, Vol. 80, No. 4, [Part 2: Physical Sciences] (Feb. 15, 1983), pp. 1137-1143 (7 pages) Many peptides and proteins that ...

The protein backbone plays a big role in protein stability. For example, hydrogen bonds between the NH of one amide and the carbonyl oxygen of another are involved in helices, sheets, and every other ...

A key role in studying the telomerase of Hansenula polymorpha was played by KFU's nuclear magnetic resonance spectrometer. "The work frequency of our NMR spectrometer with a cryo sensor is 700 MHz. It ...

In this slice through the structure of human serotonin transporter, (S)-citalopram binds to both the central (green) and allosteric (blue) binding sites. Drug designers have long been synthesizing ...
