We describe a new response to Fe-starvation in a fungal pathogen involving carbon metabolism. Pyruvate dehydrogenase (PDH) that is central to glucose metabolism is inactivated at the post-translational level in Fe-starved cells. Nevertheless, the fungal pathogen can thrive by activating backup systems for metabolizing glucose. Methods that inhibit these compensatory pathways for carbon metabolism may prove beneficial in future anti-fungal strategies.
