CC direction. {ECO:0000255|HAMAP-Rule:MF_01595}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=phosphate + RNA(n+1) = a ribonucleoside 5'-diphosphate +
CC RNA(n); Xref=Rhea:RHEA:22096, Rhea:RHEA-COMP:14527, Rhea:RHEA-
CC COMP:17342, ChEBI:CHEBI:43474, ChEBI:CHEBI:57930, ChEBI:CHEBI:140395;
CC EC=2.7.7.8; Evidence={ECO:0000255|HAMAP-Rule:MF_01595};
CC -!- COFACTOR:
CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_01595};
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_01595}.
CC -!- SIMILARITY: Belongs to the polyribonucleotide nucleotidyltransferase
CC family. {ECO:0000255|HAMAP-Rule:MF_01595}.
