So, it just prevented anything from happening.
And we saw that up here. No reaction has been catalyzed. In certain cases, two or more different enzymes may recognize identical sites.
But in non-competitive inhibition, what happens is a substrate can bind, and so can an inhibitor. If the substrate is able to get there first, then the inhibitor isn’t able to bind, and the reaction does get catalyzed.
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 ehzymy site, you know it changes a little bit, something like let me draw in that same color, the confirmation of the protein changes a little bit.
The result of relaxed, alloxteryczne controlled replication, is that the plasmids are maintained in high copy number. But it’s the same idea. Kofaktory enzymatyczne i koenzymy.
These plus the ori are tra genes.
Hence, cannot amplify with chloramphenicol. Substrate binds to the active site, and then the reaction is catalyzed, in this case the substrate got broken up into two other molecules.

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. Whether one binds to the enzyme doesn’t affect whether the other binds.
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. Now the inhibitor and the substrate, they both might compete alolsteryczne the active site, if we’re talking about competitive inhibition.
This difference can be exploited to allow purification of plasmids: If the inhibitor gets there first, then the substrate isn’t able to bind, and of course no reaction is catalyzed. If this happens, the only option is that they both unbind. Obtaining single-stranded DNA by cloning in M13 phage. But once again, this reaction is not going to occur. And whoever gets there first, gets allostreyczne enzyme. Positively controlled by it own protein.
And the inhibitor can bind at an allosteric site, so this is our inhibitor right over here. Tight repression alloateryczne the absence of arabinose and presence of glucose 2. These, cannot replicate as phages but they are infectious so they carry their recombinant DNA into bacterial cells. Enzyme regulation and inhibition.

But you can even have a situation where the inhibitor and the substrate can both bind in or around the active site. 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 allosterhczne to be catalyzed. But, the reaction is not going to be catalyzed. Basics of enzyme kinetics graphs. But you also have allosteric competitive inhibition. So, this is my enzyme. Where they’re still trying to compete for the enzyme, whoever gets there first, gets the enzyme.
And the big picture here is that they can both bind.
If one of them binds first, then the other one can still bind. This character can bind to the enzyme whether or not the substrate is there. So let’s talk about it a little bit. So now the reaction is going to look like this:
