So here we have this conformation, but here we have this confirmation. That's why we have the E two. Now, in the final step, or I shouldn't say the final step, but in the next step, we basically use a water molecule to actually hydrolyze and remove this phosphoryl group from the P domain. And as removes as it is removed, we basically form this e two stage. And in the last step of this process, what happens is as soon as that phosphorus is removed, this interconverts back into the e one stage. And so now, instead of being open this side, it is open to this side.
