Understanding Sequence-to-Structure Relationships in Proteins

The proteome is the entire set of proteins that is, or can be, expressed by a genome, cell, tissue, or organism at a certain time. It is the set of expressed proteins in a given type of cell or organism, at a given time, under defined conditions.

Proteomics is the study of the proteome.

The primary structure of a protein is crucial as it determines the overall three-dimensional structure and, consequently, the function of the protein.
