Taxonomic identifier

217992 [NCBI]

Taxonomic lineage

Bacteria › Proteobacteria › Gammaproteobacteria › Enterobacteriales › Enterobacteriaceae › Escherichia

Protein attributes

Sequence length	238 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. Also acts to regulate the attenuation of pyrE By similarity. HAMAP MF_00564
Catalytic activity	tRNA(n+1) + phosphate = tRNA(n) + a nucleoside diphosphate. HAMAP MF_00564
Sequence similarities	Belongs to the RNase PH family.
Sequence caution	The sequence AAN82903.1 differs from that shown. Reason: Erroneous initiation.
