Popis: Among human four Y-family DNA polymerases, hPol ι is exceptionally error-prone in DNA synthesis. 6 mA plays significant roles in epigenetic regulation of numerous biological processes. Nonetheless, its effects on DNA replication by hPol ι is still unclear. In this work, we found that 6 mA and Hyp, the intermediate of 6 mA, inhibited the replication of DNA by hPol ι. 6 mA lost priority in extension beyond 6 mA:T pair, partially reducing dTTP incorporation efficiency and inhibiting next-base extension. Hyp was prone to dCTP incorporation and extension beyond Hyp:C instead of Hyp:T pair. Statistically, 6 mA primarily reduced the burst incorporation rate (k
