RT   "Complete sequence of Escherichia coli C str. ATCC 8739.";
RL   Submitted (FEB-2008) to the EMBL/GenBank/DDBJ databases.
CC   -!- FUNCTION: Involved in mRNA degradation. Hydrolyzes single-stranded
CC       polyribonucleotides processively in the 3' to 5' direction (By
CC       similarity).
CC   -!- CATALYTIC ACTIVITY: Exonucleolytic cleavage in the 3'- to 5'-
CC       direction to yield nucleoside 5'-phosphates.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm (By similarity).
CC   -!- SIMILARITY: Belongs to the RNR ribonuclease family. RNase II
CC       subfamily.
CC   -!- SIMILARITY: Contains 1 S1 motif domain.
