UniProtKB - Q5FSM8 (DPO4_GLUOX)
Protein
DNA polymerase IV
Gene
dinB
Organism
Gluconobacter oxydans (strain 621H) (Gluconobacter suboxydans)
Status
Functioni
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. May be involved in translesional synthesis, in conjunction with the beta clamp from PolIII.UniRule annotation
