The selected winners are awarded Molecular Frontiers Inquiry Prize.

Early life and education Shuguang Zhang received his B.S. in biochemistry from Sichuan University in 1980 and Ph.D. in Biochemistry & Molecular Biology from University of California at Santa Barbara in 1988 (under mentorship of Eduardo Orias). The same year, he joined MIT to work with Alexander Rich.

Career and scientific work Self-assembling peptides

In 1990, Shuguang Zhang made a serendipitous discovery of a self-assembling peptide in yeast protein Zuotin. This discovery led to the development of a new field of peptide nanobiotechnology and to designs of a variety of self-assembling peptides for widespread uses, including peptide hydrogels in materials science, 3D tissue cell culture and tissue engineering, nanomedicine, sustained molecular releases, clinical and surgical applications. He co-founded a startup company 3DMatrix that brings the self-assembling peptide materials to human clinical for treatment of diabetic ulcers, bedsores (pressure ulcers) and for accelerated wound healings as well as surgical uses. Many self-assembling peptide scaffold hydrogel products have received approvals from the US FDA, European Medicine Agency (EMA), Japan Medical Agency and medical approval agency in Chengdu, China.

QTY Code

Less widely-known, Zhang invented the QTY Code as a systematic method of rendering insoluble peptide sequences water-soluble, to facilitate biochemical research, while retaining the native conformation and functionality. In 2011, Shuguang Zhang started to design membrane proteins, because there are ~26% of genes that code for membrane proteins in genomes which are crucial for both internal and external cellular communications. He conceived a simple molecular QTY Code, namely Glutamine (Q), Threonine (T) and Tyrosine (Y) to systematically replace the hydrophobic amino acids Leucine (L), Valine (V), Isoleucine (I), and Phenylalanine (F) in the 7 transmembrane alpha-helices of G protein-coupled receptors (GPCRs).
