Na+ Gradients at the Crossroads of Energy and Adaption

Blanca Barquera, Ph.D.
Associate Professor
Rensselaer Polytechnic Institute

Host: Suzanne Scarlatta, Ph.D.


The seminar will focus on the enzyme systems that manage energy and ion gradients in bacteria, with a special interest in redox-driven Na+ pumps. These systems provide crucial support for survival and proliferation in different and changing, environments because they are central to energy production, homeostasis and adaptation. We study the functions and roles of these enzyme complexes in two different contexts where they are of particular importance: (1) in the bacteria of the human colon, and (2) in two important bacterial pathogens, Vibrio cholerae, and Pseudomonas aeruginosa.
