Metalloenzymes catalyze some of the most complex chemical reactions found in Nature. The Grove lab studies and exploits a wide range of oxygen-sensitive metalloenzymes for fundamental mechanistic analysis, functional annotation and inhibitor/lead discovery. The primary focus of our lab is on catalytic iron-sulfur cluster (Fe/S) enzymes involved in human health and disease. To exploit these enzymes, the Grove lab utilizes a highly multi-disciplinary approach that includes a range of classical enzymology analyses, high-resolution crystallography, mass spectrometric methods, spectroscopic approaches (e.g., Mössbauer and electron paramagnetic resonance spectroscopies), and high-throughput inhibitor screening, that allow us to define the chemical and physical determinants responsible for substrate selectivity and reactivity. In addition, we take advantage of a variety of cell biological approaches, so as to move beyond the accrual of in vitro activities and to begin defining the complex in vivo biological functions. As a new lab, we have many projects in nascent stages:

  1. High-throughput drug discovery targeting anaerobic enzymes
  2. Metabolic profiling and optimization of novel antivirals
  3. Mechanistic understanding of Fe/S enzymes as a strategy for drug development
  4. Discovery of novel chemistry of radical SAM enzymes
  5. Anaerobic biochemistry involved in epigenetic reprogramming
