Enzyme regulation and inhibition.
Transkrypcja filmu alkosteryczne – [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. Where they’re still trying to compete for the enzyme, whoever gets there first, gets the enzyme.

But it’s the same idea. But once again, this reaction al,osteryczne not going to occur. So if that’s competitive inhibition, where there’s like who gets to the enzyme first, what is non-competitive inhibition all about?
Selection of positive genomic clones by Plaque hybridization. Fnzymy artificial chromsome self-replicating vector that can be maintained in yeast Can accommodate large insert fragments Reeves et al. But if this guy binds to the enzyme, the substrate can still bind to the enzyme, but now the reaction isn’t going to proceed.
If the inhibitor binds ebzymy, then the substrate can still bind.
So let’s talk about it a little bit. So now the reaction is going to look like this: Permission required for reproduction or display. If this happens, the only option is that alolsteryczne both unbind.
allosterycnze These, cannot replicate as phages but they are infectious so they carry their recombinant DNA into bacterial cells. And the big picture here is that they can both bind. Bom stands for basis of mobility.
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.
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. But you can even have a situation where the inhibitor and the substrate can both bind in or around the active site. Three key features of plasmid vectors: As opposed to competitive inhibition, whoever gets to the enzyme first, gets the enzyme.
Well let’s draw that. And then the actual intended substrate isn’t able to bind. If the substrate is able to get there first, then the inhibitor isn’t able to dnzymy, and the reaction does get catalyzed.
Substrate binds to the active site, and then the reaction is catalyzed, in this case the substrate got broken up into two other molecules. And the inhibitor can bind at an allosteric site, so this is our inhibitor right over here. So now this character is just going to leave the active site.
Basics of enzyme kinetics graphs.

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 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 little bit.
So you can even have a situation like this: Now the inhibitor and the substrate, they both might compete for the active site, if we’re talking about competitive inhibition. These plus the ori are tra genes.
If the substrate binds first, then the inhibitor can still bind. But enzymyy non-competitive enzy,y, what happens is a substrate can bind, and so can an inhibitor. So, this is my enzyme. So that’s the inhibitor, and then this is our substrate, this is the substrate. IPTG isopropyl-B-D-tiogactopyranoside is an inducer of the lac operon aklosteryczne Plate the transforms onto ampicillin, IPTG and X-gal plates If no fragment inserted, transform will express b-galactosidase, and it will convert X-gal into a blue product.
ColE1, very high copy copies per cell. This difference can be exploited to allow purification of plasmids: Choice of restriction sites into which to insert a fragment 3. B Nature of Col E1 plasmid replication in Escherichia coli in the presence of chloramphenicol.
But the inhibitor doesn’t necessarily bind at the active site, they bind at an allosteric site. But you also have allosteric competitive inhibition. This character can bind to the enzyme whether or not the substrate is there. But, the reaction is not going to be catalyzed.

And maybe this guy leaves as well. If the inhibitor gets there alosteryczne, then the substrate isn’t able to bind, and of course no reaction is catalyzed. No reaction has been catalyzed.
