Function
function
ATP-dependent DNA helicase important for chromosome transmission and normal cell cycle progression in G2/M. May have a role in changing DNA topology to allow the loading of proteins involved in maintaining sister chromatid cohesion in the vicinity of the centromeres. Has a specific role in chromosome segregation during meiosis II.
Catalytic activity
- ATP + H2O = ADP + phosphate + H+
- 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.
