For the past half-century, structural biologists relied on the notion that similar protein sequences give rise to similar structures and functions. While this assumption has driven research to explore ...

A protein’s three-dimensional (3D) structure, physicochemical properties and molecular function are defined by its amino-acid sequence. From the 20 commonly occurring proteinogenic amino acids, a ...

Two examples of the same molecule represented in sequence, image and graph formats are provided for direct comparison. Disclaimer: AAAS and EurekAlert! are not responsible for the accuracy of news ...

Some strange mathematical sequences are always whole numbers — until they’re not. The puzzling patterns have revealed ties to graph theory and prime numbers, awing mathematicians. Simple, yes, but ...
