Steric constraints dependent on nucleobase pair orientation vary in different DNA polymerase active sites.
Finding the right fit: Herein, we report on the development of novel steric probes and present initial insights into their interplay with DNA polymerases. Our findings provide experimental evidence for varied enzyme-substrate interactions that might account for the varied selectivity previously observed.
