UniProtKB - Q9XYU1 (MCM3_DROME)
DNA replication licensing factor Mcm3
Mcm3
Functioni
Acts as component of the Mcm2-7 complex (Mcm complex) (Mcm complex) which is the putative replicative helicase essential for 'once per cell cycle' DNA replication initiation and elongation in eukaryotic cells. The active ATPase sites in the Mcm2-7 ring are formed through the interaction surfaces of two neighboring subunits such that a critical structure of a conserved arginine finger motif is provided in trans relative to the ATP-binding site of the Walker A box of the adjacent subunit. The six ATPase active sites, however, are likely to contribute differentially to the complex helicase activity.
