Specialist enzymes make E. coli antibiotic resistant at low pH

Specialist enzymes make E. coli antibiotic resistant at low pH

New research from Arts & Sciences suggests that many “redundant” enzymes are actually specialists that ensure maximal growth across different environments. They also seem to increase resistance to antibiotics in conditions like those in the GI tract or urinary tract — raising concerns that current antibiotic susceptibility tests are inadequate.
Engineering proteins to help counter devastating diseases

Engineering proteins to help counter devastating diseases

Meredith Jackrel, assistant professor of chemistry in Arts & Sciences, recently received a five-year grant from the National Institutes of Health (NIH) and another from the Longer Life Foundation to study protein disaggregases —  evolved protein forms that mitigate protein misfolding — as a strategy to combat neurodegenerative diseases such as Alzheimer’s, Parkinson’s and ALS.
Better together: Mitochondrial fusion supports cell division

Better together: Mitochondrial fusion supports cell division

New research from Gary Patti’s laboratory in Arts & Sciences shows that when cells divide rapidly, their mitochondria are fused together. In this configuration, the cell is able to more efficiently use oxygen for energy. This work illuminates the inner workings of dividing cells and shows how mitochondria combine to help cells to multiply in unexpected ways.

Where We Come From

Ever wonder where we really come from? Washington University graduate student Cole D. Pruitt explains the connection between the stuff we’re made of, burping stars and nuclear pasta.
Washington People: Sophia Hayes

Washington People: Sophia Hayes

Sophia Hayes, associate professor of chemistry in Arts & Sciences, was an undergraduate at the University of California, Berkeley, leaning toward an economics major when she stumbled into a quantum mechanics class and then a chemistry class with a collaborative research focus. Research projects were the hook, and “I crammed the chemistry major into my last two years,” Hayes says.
