How Primary Structure Determines Protein Function Proteins are everywhere. As enzymes, they catalyse chemical reactions. There are many different types of proteins: carrier and channel proteins which transport substances, receptor proteins which are recognition site for antibodies and hormones, structural proteins which support cells and tissues, and hormones which transmit information.
Understanding the relationships between protein structure and function remains a primary focus in structural biology with important consequences in such diverse fields as molecular biology, genetics, biochemistry, protein engineering and bioinformatics. One approach to this problem is to study how nature has re-engineered proteins for new.
