Ternary complex of Y-family DNA polymerase Dpo4 with (5'S)-8,5'-Cyclo-2'-deoxyguanosine and dCTPTernary complex of Y-family DNA polymerase Dpo4 with (5'S)-8,5'-Cyclo-2'-deoxyguanosine and dCTP
Structural highlights
Function[DPO4_SULSO] Poorly processive, error-prone DNA polymerase involved in untargeted mutagenesis. Copies undamaged DNA at stalled replication forks, which arise in vivo from mismatched or misaligned primer ends. These misaligned primers can be extended by PolIV. Exhibits no 3'-5' exonuclease (proofreading) activity. It is involved in translesional synthesis.[HAMAP-Rule:MF_01113] |
