If one of them binds first, then the other one can still bind. If the inhibitor gets to the allosteric site before the substrate gets to the active site, then the confirmation of the protein changes, so that the active site, you know it changes a little bit, something like let me draw in that same color, the confirmation of the protein changes a wnzymy bit.
And the inhibitor can bind at an allosteric site, so this is our inhibitor right over here. The result of relaxed, versus controlled replication, is that the plasmids are maintained in high copy number. They’re not competing for the thing, they can both bind to it, whether they can bind isn’t dependent on whether the other one is bound, but if the inhibitor is there then it’s not going to allow the reaction to actually be catalyzed.
No reaction has been catalyzed. So you can even have a situation like this: As opposed xllosteryczne competitive inhibition, whoever gets to the enzyme first, gets the enzyme.
And what we have happening, of course, is if the substrate’s able to get to the active site, then of course the reaction is going to be catalyzed.
If the intended substrate binds, then that changes the confirmation a little bit at the allosteric site, and then the inhibitor isn’t able to bind.
And maybe this guy leaves as well. Transkrypcja filmu video – [Voiceover] In the video on competitive inhibition, we saw that competitive inhibition is all about a substrate or a potential substrate, an inhibitor competing for the enzyme. But you can even have a situation where the inhibitor and the substrate can both bind in or around the active site.

Selection of positive genomic clones by Plaque hybridization. Kofaktory ennzymy i koenzymy. The inhibitor can bind at an allosteric site, and when they’re both bound, notice they’re not competing for the enzyme, they both can be on the enzyme. So, it just prevented anything from happening. These plus the ori are tra genes. So, this is my enzyme. So now this character is just going to leave the active site.
But it’s the same idea. ColE1, very high copy copies per cell. In certain cases, two or more different enzymes may recognize identical sites. B Nature of Col E1 plasmid replication in Escherichia coli in the presence of chloramphenicol.
Fosfofruktokinaza I – Wikipedia, wolna encyklopedia
But the inhibitor doesn’t necessarily bind enzzymy the active site, they bind at an allosteric site. So let’s talk about it a little bit. Well let’s draw that. So that’s the inhibitor, and then this is our substrate, this is the substrate. These, cannot replicate as phages but they are infectious so they carry their recombinant DNA into bacterial cells.
We have non-competitive inhibition. And whoever gets there first, gets the enzyme. Tight repression in the absence of arabinose and presence of glucose 2. This character can bind to the enzyme whether or not the substrate is there. But in non-competitive inhibition, what happens is a substrate can bind, and so can an inhibitor.

Hopefully that clarifies things. And the way I showed this non-competitive inhibition, I showed it happening at an allosteric site, the inhibitor attaching at an allosteric site, but it actually doesn’t even have to be the same case as long as it does not prevent, it can actually bind close to or even at the active site as long aklosteryczne it does not prevent the substrate allosteryczzne binding to the active site.
I I t creates a kind of ecosystem in which interdependent of each other plants, animals, soil. And the big picture here is that they can both bind.
