(Phys.org)—A pair of researchers at Harvard Medical School has found an instance of a bacterial protein that behaves like a prion when inserted into another type of bacteria. In their paper published in the journal Science, ...
Ludwig Maximilian University of Munich researchers have elucidated a mechanism that recycles bacterial ribosomes stalled on messenger RNAs that lack termination codons. The protein involved provides a potential target for ...
