The question of whether amino acids in sandwich-like proteins are there to stabilize the structure or to speed up the protein-folding process is best answered by "all of the above," according ...

Researchers in Japan have clarified the structural basis for the biosynthesis of selenocysteine (Sec), an amino acid whose encoding mechanism offers clues about the origins of the genetic alphabet.

Each protein or peptide consists of a linear sequence of amino acids. The protein primary structure conventionally begins at the amino-terminal (N) end and continues until the carboxyl-terminal (C) ...

The basis for the 200-fold difference in affinity between two hybridoma antibodies specific for the hapten p-azophenylarsonate (Ars) that have diversified by somatic hypermutation was examined.

The shape, or structure, of proteins determines how they work, making it essential for researchers to have access to high-quality structural models.
