The three-dimensional shape of a protein determines its function. The shape of proteins can change by small or large amounts; another term for shape is conformation.

Description
Content

The second edition of Molecular Conformations presents the latest science in the molecular biology of protein folding. A new section contains the latest developments in establishing the mechanisms that control protein folding and – when things go wrong – protein degradation. While the new section is more scientifically involved that the original sections, it has been written in a way that puts the emphasis on general concepts.
