Comments
[?]
FUNCTION | DNA-dependent ATPase and ATP-dependent 5'-3' DNA helicase. Has no activity on blunt DNA or DNA with 3'-overhangs, requires at least 10 bases of 5'-ssDNA for helicase activity. |
CATALYTIC ACTIVITY | Reaction=Couples ATP hydrolysis with the unwinding of duplex DNA at the replication fork by translocating in the 5'-3' direction. This creates two antiparallel DNA single strands (ssDNA). The leading ssDNA polymer is the template for DNA polymerase III holoenzyme which synthesizes a continuous strand.; EC=5.6.2.3; |
CATALYTIC ACTIVITY | Reaction=ATP + H2O = ADP + H(+) + phosphate; Xref=Rhea:RHEA:13065, ChEBI:CHEBI:15377, ChEBI:CHEBI:15378, ChEBI:CHEBI:30616, ChEBI:CHEBI:43474, ChEBI:CHEBI:456216; EC=5.6.2.3; |
SIMILARITY | Belongs to the RecD family. RecD2 subfamily. |

Comments | The RecD2 helicase is not associated with RecB and RecC, although a few organisms have both genes. Its physiological role varies in the few bacteria where it has been characterized. |
