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 complex with tRNA, CTP, ethanediol and Ca+2 ion (PDB entry 3ovs).
