The layout of this reaction may differ from that in the pathway view due to the constraints in pathway layout
At the beginning of this reaction, 1 molecule of 'ATP', and 1 molecule of 'pre-replicative complex' are present. At the end of this reaction, 1 molecule of 'phosphorylated Orc1', 1 molecule of 'pre-replicative complex (Orc1-minus)', and 1 molecule of 'ADP' are present.

This reaction takes place in the 'nucleus' and is mediated by the 'kinase activity' of 'Cyclin A:Cdk2 complex'.
