Protein attributes

Sequence length	1634 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Inferred from homology.

General annotation (Comments)

Catalytic activity	Deoxynucleoside triphosphate + DNA(n) = diphosphate + DNA(n+1).
Post-translational modification	This protein undergoes a protein self splicing that involves a post-translational excision of the intervening region (intein) followed by peptide ligation Potential.
Sequence similarities	Belongs to the DNA polymerase type-B family. Contains 2 DOD-type homing endonuclease domains.
