These simplified images from Wayne Anderson's lab show how the polypeptide backbone of a Bacillus anthracis protein folds and curls around itself like a ribbon. It is one of 5,617 proteins in the ...

A molecular model of the F12 biotherapy shows the fold of its polypeptide backbone. Residual T cell epitopes are mapped onto the structure and colored from white (no epitopes) to dark red (dense ...

Proteins are distinct from one another with respect to their number, type, and sequence of amino acids making up the polypeptide backbone. Therefore, they have unique nutritional attributes, ...
