General annotation (Comments)

Function	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. Once loaded onto DNA, double hexamers can slide on dsDNA in the absence of ATPase activity. Necessary for cell growth. Ref.7 Ref.8
Catalytic activity	ATP + H₂O = ADP + phosphate.
Subunit structure	Component of the MCM2-7 complex. The complex forms a toroidal hexameric ring with the proposed subunit order MCM2-MCM6-MCM4-MCM7-MCM3-MCM5; loaded onto DNA, forms a head-head double hexamer. Interacts with CSM1. Ref.7 Ref.8 Ref.11
Subcellular location	Nucleus.
Miscellaneous	Present with 35100 molecules/cell in log phase SD medium. Early fractionation of eukaryotic MCM proteins yielded a variety of dimeric, trimeric and tetrameric complexes with unclear biological significance. The MCM2-7 hexamer is the proposed physiological active complex.
Sequence similarities	Belongs to the MCM family. Contains 1 MCM domain.
