1 Here, Dnl4 catalytic point mutants were generated that were severely defective in auto-adenylation in vitro and NHEJ activity in vivo, despite being hyper-recruited to DSBs and supporting wild-type levels of Lif1 interaction and assembly of a Ku- and Lif1-containing complex at DSBs. dsbs DNA ligase (ATP) DNL4 Saccharomyces cerevisiae S288C

3 Enrichment of DNA ligase I (Cdc9 in yeast) at DSBs was observed in wild-type as well as dnl4 point mutant strains, with both Dnl4 and Cdc9 disappearing from DSBs upon 5" resection that was unimpeded by the presence of catalytically inactive Dnl4. dsbs DNA ligase (ATP) DNL4 Saccharomyces cerevisiae S288C
