The enzyme tRNA-guanine transglycosylase (TGT) chemically modifies transfer RNA (tRNA) and plays a key role in how disease-causing bacteria control the production of proteins needed to cause infection. E. coli TGT is nearly identical to the one found in Shigella, which causes
Many people drive more carefully for a while after receiving a traffic fine. But do large corporations, such as airlines, also change their behavior when they face financial penalties? We examine this question by studying penalties imposed in the United States for lengthy
Researchers at the University of Twente have developed an optical method that follows the shape changes of a single protein in liquid without attaching anything to it. It reads the protein's structure from its own molecular vibrations, free from the labels or tags that other
