Science & Technology

Scientists at Washington University in St. Louis described for the first time the structure of a bifunctional protein, called CcsBA, that transports heme and attaches it to cytochromes. The study led by Robert Kranz, professor of biology in Arts & Sciences, captured two conformational states of CcsBA, a bacterial and chloroplast protein, allowing researchers to characterize the enzyme mechanism.

A collaboration between Washington University in St. Louis, Université de Montréal and McGill University discovers a new importance of biomolecular condensates.

Research from the lab of Kimberly Parker at the McKelvey School of Engineering looks at the interactions of different herbicides and what they mean for herbicide drift.
