MCM Helicase

A DNA helicase essential for unwinding the DNA double helix during replication and chromosome segregation within the cell cycle.

The statement of the theorem

Define the DNA unwinding process by the helicase enzyme H\mathcal{H} acting on a double helix segment of length LL. Let N(t)N(t) be the number of base pairs unwound at time tt. The rate of unwinding is governed by the kinetic equation:\ndNdt=kunwind[MCM](11+KM/[ATP])kreanneal(NNeq)\frac{d N}{d t} = k_{unwind} \cdot [MCM] \cdot \left( \frac{1}{1 + K_M / [ATP]} \right) - k_{reanneal} \cdot (N - N_{eq})\nwhere kunwindk_{unwind} is the maximum unwinding rate, [MCM][MCM] is the concentration of the MCM complex, and kreannealk_{reanneal} models the rate of spontaneous reannealing, ensuring the process is thermodynamically favorable (ΔG<0\Delta G < 0 for unwinding).
