title: In vitro processing of E. coli tRNA precursors.
abstract: Using E. coli tRNA precursors isolated from an RNAase P mutant strain, we have studied the steps required for the formation of tRNAs having a mature primary sequence in vitro. Our results suggest that at least three different enzymatic activities can participate in the processing of tRNA precursors.
