Abstract

Two Bacillus subtilis tRNAHis precursors (Green, C. J., and Vold, B. S. (1988) J. Biol. Chem. 263, 652-657) were processed by Escherichia coli RNase P in the presence of varying [Mg2+]. The wild type precursor was processed under all conditions to afford a single tRNA product containing 8 base pairs in the acceptor stem. In contrast, the position of processing of a mutant tRNAHis precursor (containing a G27 ↔ A27 alteration) was shown to be condition-dependent. Processing occurred at A27 under conditions consistent with forma-tion of an A27-C100 base pair in the acceptor stem but at G28 under conditions that disfavored base pair formation. The ability to control the site of RNase P-mediated tRNA precursor processing is unprecedented and permits analysis of the chemical factors that promote processing.
