The crystal structure of a natural DNA polymerase complexed with mirror DNA.
Chem Commun (Camb). 2020 Feb 18;56(14):2186-2189. doi: 10.1039/c9cc09351f. Epub, 2020 Jan 23.
The intrinsic l-DNA binding properties of a natural DNA polymerase was discovered. The binding affinity of Dpo4 polymerase for l-DNA was comparable to that for d-DNA. The crystal structure of Dpo4/l-DNA complex revealed a dimer formed by the little finger domain that provides a binding site for l-DNA.
