( A ) <t>NMP-seq</t> methodology. Genomic DNA was first sonicated to short fragments (~400 bp) and ligated to the 1st adaptor (green). After blocking all free 3’-OH groups with terminal transferase and dideoxy-ATP (dd), DNA fragments were digested with AAG <t>and</t> <t>APE1</t> to generate a new nick with a ligatable 3’-OH group at the NMP damage site. After denaturing to obtain single-stranded DNA, the new 3’ end is ligated to a splint adaptor (2nd adaptor; purple) and the ligation occurs exactly at the damage site. The biotin on the 2nd adaptor allows purification of ligation product with the Streptavidin beads. The purified product is used as the template for PCR amplification, using primers complementary to the 1st and 2nd adaptors. The resulting library is sequenced on an Iron Torrent sequencer using a sequencing primer complementary to the 2nd adaptor. ( B ) NMP-seq read counts in MMS-treated mag1 cells (0.4% MMS for 10 min).
