Welcome to the Stroupe Lab

How do bacteria reduce sulfur for building amino acids and cofactors?

How do bacteria synthesize siroheme, a unique tetrapyrrole used for sulfur metabolism?

The active site of Sulfite Reductase Hemoprotein with sulfite bound to the active site siroheme
The first structure of the Sulfite Reductase flavoprotein containing all three domains shows it adopts a highly extended conformation that is unique to this homolog (Tavolieri, et al, 2019)

The Stroupe lab is interested in answering these questions using an interdisciplinary biochemical and structural biological approach.
