title: Recognition of a non-standard base pair by thermostable DNA polymerases.
abstract: Examination of several commercially available thermostable DNA polymerases identifies 9 degrees N DNA polymerase as single enzyme that could incorporate two components of an expanded genetic alphabet, 2,4-diaminopyrimidine and xanthosine as deoxynucleoside triphosphate opposite their cognate base in a DNA template.
