Pocket wall interactions are not required for NEIL1 activity against 5caC: The glycosylase activities of NEIL1 and of the indicated variants were tested by incubation with dsDNA substrates containing a 5OHC, 5fC or 5caC base (32P radiolabelled in the modified strand). After 1 hour incubation of 20 nM dsDNA with 200 nM enzyme at 37 °C, the samples were treated with NaOH to induce single strand breaks at abasic sites. Cleavage products were analysed by denaturing gel electrophoresis and visualized by autoradiography.
