Genet. 35:32-40(2003). CC -!- FUNCTION: Catalyzes the addition and repair of the essential 3'- CC terminal CCA sequence in tRNAs without using a nucleic acid CC template. Adds these three nucleotides in the order of C, C, and A CC to the tRNA nucleotide-73, using CTP and ATP as substrates and CC producing inorganic pyrophosphate (By similarity). CC -!- CATALYTIC ACTIVITY: ATP + tRNA(n) = diphosphate + tRNA(n+1). CC -!- CATALYTIC ACTIVITY: CTP + tRNA(n) = diphosphate + tRNA(n+1). CC -!- COFACTOR: Magnesium (By similarity). CC -!- MISCELLANEOUS: A single active site specifically recognizes both CC ATP and CTP and is responsible for their addition (By similarity). CC -!- SIMILARITY: Belongs to the tRNA nucleotidyltransferase/poly(A) CC polymerase family. Bacterial CCA-adding enzyme type 2 subfamily.
