Protein attributes

Sequence length	874 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Inferred from homology

General annotation (Comments)

Function	Participates in initiation and elongation during chromosome replication; it exhibits DNA-dependent ATPase activity By similarity. The intein is an endonuclease Potential.
Catalytic activity	ATP + H₂O = ADP + phosphate.
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.
Sequence similarities	Belongs to the helicase family. DnaB subfamily. Contains 1 DOD-type homing endonuclease domain. Contains 1 SF4 helicase domain.
