Protein attributes

Sequence length	241 AA.
Sequence status	Complete.
Protein existence	Inferred from homology

General annotation (Comments)

Function	Phosphorolytic exoribonuclease that removes nucleotide residues following the -CCA terminus of tRNA and adds nucleotides to the ends of RNA molecules by using nucleoside diphosphates as substrates By similarity. HAMAP-Rule MF_00564
Catalytic activity	tRNA(n+1) + phosphate = tRNA(n) + a nucleoside diphosphate. HAMAP-Rule MF_00564
Sequence similarities	Belongs to the RNase PH family.
