So we see that the theory in 195 in its alcohol form is simply not a strong enough nuclear file. And to transform it into a better nuclear file, a nearby HistoGene 57 pulls away the hydrogen ion to form an alcoxide and to actually position the histidine so that these two residues can interact very well. This Aspartate uses its full positive charge to basically position and move this histidine side chain in the correct orientation. And together this catalytic triad, as we'll see in just a moment, actually promotes the cleavage of the peptide bond. So let's actually discuss what the reaction mechanism is. So what are the details of the reaction mechanism that takes place inside the active side of climate?
