Stark, Ruth E.

One or more keywords matched the following properties of Stark, Ruth E.

Property	Value
overview	The Stark Laboratory uses structural biology approaches to study plant protective polymers, lipid metabolism, and potentially pathogenic melanized fungal cells. Nondestructive study of the molecular and mesoscopic architectures underlying the integrity of cuticles in natural and engineered tomatoes and potatoes is undertaken using solid-state nuclear magnetic resonance (NMR), atomic force microscopy, and mass spectrometry. Ligand recognition and peroxisome proliferator-activated receptor interactions of fatty acid-binding proteins are under investigation by solution-state NMR. The molecular structure and development of melanin pigments within fungal cells is probed using (bio)chemical synthesis and solid-state NMR.
