Ribonuclease PH

Gene

rph

Organism
Parvibaculum lavamentivorans (strain DS-1 / DSM 13023 / NCIMB 13966)
Status
Reviewed-Annotation score: -Protein inferred from homologyi

Functioni

Phosphorolytic 3'-5' exoribonuclease that plays an important role in tRNA 3'-end maturation. Removes nucleotide residues following the 3'-CCA terminus of tRNAs; can also add nucleotides to the ends of RNA molecules by using nucleoside diphosphates as substrates, but this may not be physiologically important. Probably plays a role in initiation of 16S rRNA degradation (leading to ribosome degradation) during starvation.UniRule annotation

Catalytic activityi

tRNA(n+1) + phosphate = tRNA(n) + a nucleoside diphosphate.UniRule annotation
