Functional protein building blocks could be used to fabricate tunable, dynamic materials

Abstract:
Proteins, large organic compounds made of amino acids, provide many of the most basic units of function in living systems. They make up about half of the dry mass of animals and humans. There may be as many as 1 million different types of proteins in the human body (it is estimated that the human proteome is comprised of an average of 5-7 protein isoforms per open reading frame in the human genome and a further 600 000-odd immunoglobulins present in serum at any given moment) - nobody really knows. The word protein comes from the Greek prota, meaning 'of primary importance', and they actually may become of great importance in nanoscale fabrication as well. Proteins have an amazing number of functions inside our bodies: Enzymes serve as catalysts to break down food into various components; transport proteins such as hemoglobin transport molecules (e.g. oxygen); storage proteins store molecules (e.g. iron is stored in the liver as a complex with the protein ferritin); structural proteins such as keratin or collagen are needed for mechanical support in tissues like cartilage and skin but also hair and nails; proteins are the major component of muscles and for instance actin or myosin are key to contracting muscle fibers; hormones control the growth of cells and their differentiation; antibody proteins are needed for immune protection; and toxins are, well, toxic, but in minute amounts could have beneficial medical properties. Scientists believe that this variety of natural protein functions - actuation, catalysis, structural transport and molecular sequestering - could serve as valuable and versatile building blocks for synthesis of functional materials. Researchers now have found that nanometer-scale changes in protein conformation can be translated into macroscopic changes in material properties. The result is a new class of dynamic, protein-based materials.
