rRNA processing by 3'-5' exoribonuclease DinG
DinG is a protein that in firmicutes consists of an N-terminal nuclease domain and a C-terminal DEAH helicase-like domain. In bacterium Listeria monocytogenes under conditions of ribosome maturation intermediate accumulation, DinG initiates ribosomal RNA (rRNA) degradation of ribosome precursors.
