Ag super(I) Ion Mediated Formation of a C-A Mispair by DNA Polymerases

Silver turns up the A-C: In the presence of Ag super(I) ions, a DNA polymerase incorporated deoxyadenosine (from dATP) at the site opposite cytosine in the template strand to afford the full-length product (see scheme), meaning that DNA polymerases prefer a C-Ag super(I)-A base pair to the more ther...

Zusammenfassung:Silver turns up the A-C: In the presence of Ag super(I) ions, a DNA polymerase incorporated deoxyadenosine (from dATP) at the site opposite cytosine in the template strand to afford the full-length product (see scheme), meaning that DNA polymerases prefer a C-Ag super(I)-A base pair to the more thermodynamically stable C-Ag super(I)-C base pair.
