Binding
Enzymatic Assay: Fluorogenic biochemical assays used recombinant full-length FEN-1 or catalytic domains of Exo1, XPG or GEN1 and 200 nM of a DNA substrate (formed by annealing three oligonucleotides—quencher (5′-CAC GTT GAC TAC CGC TCA ATC CTG ACG AAC ACA TC-BHQ2), flap (5′-TAMRA-GA TGT CAA GCA GTC CTA ACT TTG AGG CAG AGT CCG C) and template (5′-GC GGA CTC TGC CTC AAG ACG GTA GTC AAC GTG-3′) (PMID: 21062821)) in 50 mM Tris pH 8.0, 10 mM MgCl2, 1 mM DTT, and 0.01% Tween-20. Inhibitors arrayed in dose response were added from DMSO stocks (using a V&P 384-pintool head) to the enzyme solution in low volume, black polystyrene 384-well plates (Corning #3677) 15 minutes prior to the addition of the DNA substrate. Reactions were allowed to proceed for 2-4 hours at 25° C. or 37° C. Fluorescence data (Excitation: 530 nm/10 nm bandwidth; Emission: 590 nm/20 nm bandwith) were measured with an Infinite M1000 plate reader (Tecan).
