DE RecName: Full=Ribonuclease PH; DE Short=RNase PH; DE EC=2.7.7.56; DE AltName: Full=tRNA nucleotidyltransferase; GN Name=rph; OrderedLocusNames=Atc_2268; OS Acidithiobacillus caldus (strain SM-1). OC Bacteria; Proteobacteria; Gammaproteobacteria; Acidithiobacillales; OC Acidithiobacillaceae; Acidithiobacillus. OX NCBI_TaxID=990288; RN [1] RP NUCLEOTIDE SEQUENCE [LARGE SCALE GENOMIC DNA]. RC STRAIN=SM-1; RX PubMed=21703548; DOI=10.1016/j.jgg.2011.04.006; RA You X.Y., Guo X., Zheng H.J., Zhang M.J., Liu L.J., Zhu Y.Q., Zhu B., RA Wang S.Y., Zhao G.P., Poetsch A., Jiang C.Y., Liu S.J.; RT "Unraveling the Acidithiobacillus caldus complete genome and its RT central metabolisms for carbon assimilation."; RL J. Genet. Genomics 38:243-252(2011). CC -!- FUNCTION: Phosphorolytic exoribonuclease that removes nucleotide CC residues following the -CCA terminus of tRNA and adds nucleotides CC to the ends of RNA molecules by using nucleoside diphosphates as CC substrates (By similarity). CC -!- CATALYTIC ACTIVITY: tRNA(n+1) + phosphate = tRNA(n) + a nucleoside CC diphosphate. CC -!- SIMILARITY: Belongs to the RNase PH family.
