CC -!- FUNCTION: This protein acts as a DNA primase generating di- to
CC pentaribonucleotides; the predominant product being the dimer pppApG.
CC It complexes specifically to the P4 origin of replication (ori) and its
CC cis replication region (crr). It also acts as a DNA helicase.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=ATP + H2O = ADP + H(+) + phosphate; Xref=Rhea:RHEA:13065,
CC ChEBI:CHEBI:15377, ChEBI:CHEBI:15378, ChEBI:CHEBI:30616,
CC ChEBI:CHEBI:43474, ChEBI:CHEBI:456216; EC=3.6.4.12;
CC -!- SUBUNIT: Homohexamer.
