The amino acid sequence of a protein encodes its three-dimensional structure and determines its biological function. Although researchers can readily generate proteins with altered amino acid ...

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

The three-dimensional shape of a protein determines its function. This is because proteins form attachments and interact with many other molecules and structures inside organisms. The shape of a ...

Amino acids are the building blocks that form polypeptides and ultimately proteins. Consequently, they are fundamental components of our bodies and vital for physiological functions such as protein ...

A University of Iowa-led study has revealed the unexpected structure adopted by the DNA repair protein RAD52 as it binds and ...

In Greek mythology, Proteus, son of Poseidon and prophetic shepherd of sea-beasts, could foretell the future. The elusive sea god was difficult to capture as he assumed many forms—a lion, a serpent, ...

Although the rational protein design approach offers an increased possibility of beneficial alterations, it is not easy to accurately predict the sequence-structure-function relationship, particularly ...

The double ring, spool-like structure of RAD52 protects replicating DNA in dividing cells. A study led by the University of ...

Harvard Medical School scientists have identified a key protein in the human immune system that drives inflammatory and ...

The information DNA contains is the instructions that the cell uses to make proteins. Proteins play a big part in determining the characteristics of specialised cells and whole organisms.
