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.[1] |
