The peptidyl-tRNA hydrolase (Pth) enzyme plays an essential role in recycling tRNA from peptidyl-tRNA that has prematurely dissociated from the ribosome. In this study of Escherichia coli Pth, the critical role of histidine 20 was investigated by site-directed mutagenesis, stopped-flow kinetic measurements, and chemical modification. The histidine residue(More)
