Welcome to the Center for the Study of Systems Biology at Georgia Tech

What is Systems Biology?

Recognized by most experts in the field as the future of biology, Systems Biology seeks to understand how complex living systems interact with each other so that we can diagnose and treat disorders such as cancer. While past biological research has taught us much about how these individual biological units are structured and function, future biology will be focused on understanding how these units interact.

Vision of the Center for the Study of Systems Biology

With the completion of the sequencing of the human genome, the possibility exists to unlock the secrets of life and with such understanding, powerful new approaches to the treatment of disease will emerge. Read More →

Origin of Life’s Handedness and Protein Biochemistry

Examine your hands. The right is a mirror image of the left. They look very similar, but you know they’re not when you try to put your left hand inside a right glove.

The molecules of life have a similar handedness. Proteins for example are like your left hand, made up of amino acids that are all left-handed. This phenomenon is called chirality. How chiral systems emerged is one of the key questions of origins-of-life research.

On the possible origin of protein homochirality, structure, and biochemical function

Living systems contain mainly chiral macromolecules, including proteins. How L-chiral proteins emerged from demi-chiral mixtures is unknown. Our simulations show that, compared to contemporary proteins, demi-chiral proteins have shorter regular secondary structures due to fewer internal hydrogen bonds, but similar global folds and small molecule binding sites. Demi-chiral proteins contain L-chiral substructures matching native active site geometries. Among the most frequently generated enzymes with native active site residues are ancient functions associated with metabolism and replication. This suggests that demi-chiral proteins could engage in early metabolism, creating the feedback loop for transcription and cell formation partly responsible for life’s emergence.
