title: Maturation of 23S rRNA in Bacillus subtilis in the absence of Mini-III.
abstract: 23S rRNA maturation in Bacillus subtilis is catalyzed by the recently characterized enzyme Mini-RNase-III. Mini-III is dispensable, however, and 23S rRNA is matured by other ribonucleases in strains lacking this enzyme. Here we show that these RNases are the 5'-to-3' exoribonuclease RNase J1 and the 3'-to-5' exoribonucleases, principally RNase PH and YhaM.
