The article presents a study on the ribonuclease activity of enzymes including RNase J1, RNase J2, and RNase Y, produced by Bacillus Subtilis. Shahbabian and colleagues studied the ribonuclease turnover in Bacillus subtilis, which focused on the degradation fo the S-adenoylmethionine (SAM)-dependent yitJ riboswitch. They concluded that the loss of RNase Y, mRNA decay will be reduced.
