'''Mechanism:''' The mechanism is the following: The histidine will react with the serine and deprotonate it. '''The deprotonated hydroxyl group of the serine will act as a nucleophilic species''' and attack the carbon from the carbonyl function on the peptide. This will lead to the formation of a tetrahedral intermediate. Then, a second tetrahedral intermediate will be formed, but with the attack of a deprotonated water molecule. At the end, the regeneration of the active site will be done with the release of the peptide cut in two parts. | '''Mechanism:''' The mechanism is the following: The histidine will react with the serine and deprotonate it.
