Ye's Ph.D. work was focused on protein engineering and enzyme kinetics. She developed a fluorescence reporting system to monitor the structural changes coupled with chemical events of pyruvate phosphate dikinase (PPDK) catalyzed reaction, elucidated the compositions of PPDK active site in catalysis and substrate binding to assist rational design of chemical inhibitors of PPDK, and identified crucial molecular structure at the domain interfaces of PPDK.

Research Interests

Protein Engineering and Kinetics

Ye established the roles of chemical interactions in domain communication and catalysis of PPDK by employing steady state and transient state kinetic analysis. She facilitated the crystal structure analysis of conformational change of PPDK under different catalytic stages by altering the molecular structure of the enzyme, chemical interactions at domain interface, and domain linker structure. Additionally, Ye investigated the role of the domain linkers in separate site catalysis and examined the structure, stability, and catalytic potential in the Engineered Phosphoryl Carrier Domain of PPDK.

Cell Signaling Pathway Regulations

Ye examined the regulatory mechanisms of signaling pathways in cytokine induced intestinal epithelial tight junction malfunction and investigated the role of myosin light chain kinase in tight junction barrier modulation.

Nerve Agent Countermeasure Development

Ye assisted in the cell-free protein synthesis of rationally-designed unnatural amino acid to re-engineer a nerve agent degrading enzyme.

Biomarker Identification using Mass-Spectrometry

Ye developed NanoFlow-MS, UPLC-MS and ASAP-MS methods for biomarker identification.
