Comments:
-!- FUNCTION: 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 (By similarity).
-!- CATALYTIC ACTIVITY: Deoxynucleoside triphosphate + DNA(n) =
diphosphate + DNA(n+1).
-!- COFACTOR: Binds 2 magnesium ions per subunit (By similarity).
-!- SUBUNIT: Monomer (By similarity).
-!- SUBCELLULAR LOCATION: Cytoplasm (Probable).
-!- SIMILARITY: Belongs to the DNA polymerase type-Y family.
-!- SIMILARITY: Contains 1 umuC domain.
