'''CCA-adding enzyme''' (CAE) builds or repairs the trinucleotice CCA at the 3’ end of tRNA. CAE has one active site which is capable of binding CTP and ATP in a specific sequence. In the bacteria Aquifex aeolicus, CAE consists of 2 subunits. One specific for CTP and the other for ATP. CAE builds the CCA without a genetic template. | '''CCA-adding enzyme''' (CAE) builds or repairs the trinucleotice CCA at the 3’ end of tRNA.
