Polyadenylation helps regulate functional tRNA levels in Escherichia coli
Here we demonstrate a new regulatory mechanism for tRNA processing in Escherichia coli whereby RNase T and RNase PH, the two primary 3′ → 5′ exonucleases involved in the final step of 3′-end maturation, compete with poly(A) polymerase I (PAP I) for tRNA precursors in wild-type cells. In the absence...
