Deskripsi

DNA Ligase IV (LigIV) catalyzes nick sealing of DNA double-strand break substrates during non-homologous end-joining. Here the authors present the crystal structures of two human LigIV DNA-bound catalytic states, which provide insights into its catalytic mechanism and the molecular basis of LIG4 syndrome causing disease mutations.
