- | The <scene name='72/725332/Active_site/1'>active site</scene> involves the residues SER 195, HIS 57, Asp 102 and GLY 193 in which the trypsin substrate forms a stable tetrahedral intermediate upon the formation of H-bonds located in what is known as the "oxyanion hole". This preferential binding of the enzyme-substrate complex of the acyl-enzyme intermediate is responsible for much of the catalytic efficiency of serine proteases. | + | The main transition state of interest of interest is the <scene name='72/725332/Acyl-intermediate/1'>acyl-intermediate</scene>which forms when the peptide bond of the newly bound substrate complex (as a tetrahedral intermediate) is cleaved yielding a carbonyl group on SER 195.

- | This is a sample scene created with SAT to <scene name="/12/3456/Sample/1">color</scene> by Group, and another to make <scene name="/12/3456/Sample/2">a transparent representation</scene> of the protein. You can make your own scenes on SAT starting from scratch or loading and editing one of these sample scenes. | ||
