A Models of the large fragment of polymerase I of CDA (green), large Klenow fragment of E. coli DNA polymerase I (cyan) and Thermus aquaticus DNA polymerase I (purple). See Tables S10A–C for corresponding protein and domain IDs. B Enlarged view of the 3′-5′ exonuclease site and RNaseH-like catalytic residues. C Experimental evaluation of the fidelity of CDA DNA polymerase I, in comparison to Taq and Bst polymerases.
