Organism
Escherichia coli (strain K12)
Function
3'-to-5' exoribonuclease specific for small oligoribonucleotides 2 to 5 nucleotides in length, as well as small (2 to 5 nucleotides) ssDNA oligomers. Probably responsible for the final step in mRNA degradation.
Similarity
Belongs to the oligoribonuclease family.
