Abstact

Replicate it: Structures of KOD and 9°N DNA polymerases, two enzymes that are widely used to replicate DNA with highly modified nucleotides, were solved at high resolution in complex with primer/template duplex. The data elucidate substrate interaction of the two enzymes and pave the way for further optimisation of the enzymes and substrates.
