DESCRIPTION

Also known as MCM7_DROME, Mcm7. Acts as component of the Mcm2-7 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. Component of the Mcm2-7 complex. The complex forms a toroidal hexameric ring with the proposed subunit order Mcm2-Mcm6-Mcm4-Mcm7-Mcm3-Mcm5 (Probable).
