  1. A directed evolution design of target specificity and kinetic analysis of conformational transitions in the HhaI methyltransferase /

    … A new method to follow the target cytosine flipping and its subsequent covalent activation has been proposed, which allows a direct real-time observation of these processes by monitoring associated UV absorbance changes in a chemically unperturbed DNA. These studies for the first time …

    … with the experiment. In the examination of the base-flipping mechanism of the DNA, in which Beuck and Weinhold have replaced a base with the appropriate thiobase at different positions of the DNA (Beuck, Promotion 2004, RWTH-Aachen), the theoretical spectra show qualitatively the same change …

    … cavity in the major groove side, which may allow base flipping and dGTP insertion opposite -BP, while k/IV/Dbh-type polymerases do not. When this cavity is plugged in Dpo4 by mutagenesis or the introduction of an N-clasp motif, dGTP rates increase by nearly 20-fold. In conclusion, this data …

    … understand the conformational dynamics of uracil base flipping and how small molecules might interact in this binding mode but also to the development of new ligands through structure-based drug design. The design of base binding ligands was validated by X-ray crystallography. These principles are …
