Characterization of tRNA(Cys) processing in a conditional Bacillus subtilis CCase mutant reveals the participation of RNase R in its quality control.

Microbiology (Reading, England) - 1 Jul 2010

Abstract excerpt

We generated a conditional CCase mutant of Bacillus subtilis to explore the participation in vivo of the tRNA nucleotidyltransferase (CCA transferase or CCase) in the maturation of the single-copy tRNA(Cys), which lacks an encoded CCA 3' end. We observed that shorter tRNA(Cys) species, presumably lacking CCA, only accumulated when the inducible Pspac : cca was introduced into an rnr mutant strain, but not in...
