How to Build a Better Protein: Advances in Biomolecular Engineering
Posted September 14, 2007
Chemical engineers have long envied the elegant way that biological enzymes perform their tasks. These molecules, usually proteins, catalyze complex chemical reactions under mild temperature, pressure, and pH conditions. They work in aqueous solution, without the need for organic solvents. And perhaps most attractively, they can be exquisitely selective in their choice of substrates and the specificity of their products.
Protein engineers are looking to pick up where evolution left off and design proteins that can make plastic-like polymers and carry out other desirable reactions under mild conditions. They are also working to improve or change the functions of proteins with potential medical or bioengineering uses, such as monoclonal antibodies or the structural protein collagen. On May 22, 2007, seven such engineers presented their work to others in their field at a conference titled Advances in Biomolecular Engineering: Protein Design Symposium, held at the Polytechnic University in Brooklyn, NY.
