UniProtKB - O54453 (RNAAM_SALTY)
Protein
5'-3' exoribonuclease
Gene
trpH
Organism
Salmonella typhimurium (strain LT2 / SGSC1412 / ATCC 700720)
Status
Functioni
Efficiently catalyzes the hydrolysis of the 3'-phosphate from 3',5'-bis-phosphonucleotides as well as the successive hydrolysis of 5'-phosphomononucleotides from the 5'-end of short pieces of RNA and DNA, with no specificity toward the identity of the nucleotide base. Is more efficient at hydrolyzing RNA oligonucleotides than DNA oligonucleotides. This enzyme can also hydrolyze annealed DNA duplexes, albeit at a catalytic efficiency lower than that of the corresponding single-stranded oligonucleotides.
