Name  tRNA adenylyltransferase Short Name  tRNA_adenylyltransferase
Type  Family Description  The enzyme tRNA adenylyltransferase, also called tRNA-nucleotidyltransferase and CCA-adding enzyme, can add or repair the required CCA triplet at the 3 -end of tRNA molecules. Genes encoding tRNA include the CCA tail in some but not all bacteria, and this enzyme may be required for viability. Members of this family represent a distinct clade within the larger family (tRNA nucleotidyltransferase/poly(A) polymerase family protein). The example from Streptomyces coelicolorwas shown to act as a CCA-adding enzyme and not as a poly(A) polymerase.
