dc.description.abstract | When the rnpB gene encoding M1 RNA, the RNA component of Escherichia coli RNase P, is transcribed, the primary M1 RNA transcript (pM1 RNA) is produced and subsequently processed at the 3' end to generate the mature M1 RNA, To study features of pM1 RNA thought to be involved in RNA processing, systematic mutations were introduced, in sequence elements and secondary structures surrounding the processing site using p23 RNA, a truncated pM1 RNA transcribed from the internally deleted, rnpB gene, as a model substrate and the processing of its mutant derivatives was analyzed in vivo and in vitro. Neither the alteration of two bases forming the processing site nor the disruption of secondary structures surrounding the site significantly affected the processing efficiency although the secondary structures were required for maintaining RNA stability. In contrast, mutations at the rne-dependent site, GAUUU, immediately 3' to the processing site inhibited the processing and the extent of the inhibition varied with the altered sequences. Furthermore, the processing of the mutants of the rne-dependent site as well as wild-type p23 RNA was inhibited in an E. coli rne(ts) strain at the nonpermissive temperature. | - |
