What is it:
Serine Proteases (SP) are a class of enzymes that cut peptide bonds in proteins. They are involved with basic functions, such as food digestion, and inflamation/immunity. It is called "serine" proteases because the catalytic activity is due to a Serine protein residue.
How does it work:
The Serine protein residue is part of a catalytic triad containing Ser195, His 57, Asp 102. The asp (negative) draws protons on the His, which in turn pulls on protons on the ser. This tug-a-war like mechanism makes the ser nucleophilic, so that it can react with the protein and cause cleaving of the bond. The reaction involves a tetrahedral intermediate with the substrate (protein), acyl enzyme intermediate, and a tetrahedral intermediat with water to reset the process and regenerate the enzyme. The enzyme goes through intermediates because it is energetically favored (enzyme induces intermediate for which it has higher affinity), so that it can drive the reaction towards catalysis.
How is it regulated:
Via natural inhibitors, and proforms of the enzyme (zymogens).

Where is protease released?
Proteases are currently classified into six broad groups: Serine proteases Threonine proteases Cysteine proteases Aspartate proteases Metalloproteases Glutamic acid proteases. Quote, please, which type of protease are you referring to ?
What type of molecule is proteases?
Proteases are enzymes, which are a type of protein molecule. They catalyze the breakdown of other proteins by hydrolyzing peptide bonds, facilitating various biological processes such as digestion, cell regulation, and protein recycling. Proteases can be classified into different types based on their catalytic mechanisms, including serine, cysteine, aspartic, and metalloproteases.
What is the optimum Ph in protease?
The optimum pH for proteases can vary significantly depending on the specific enzyme and its source. Generally, most proteases function best in the acidic to neutral range, with many serine proteases operating optimally around pH 7-8, while pepsin, a gastric protease, works best at a pH of around 1.5-2.0. It's essential to consider the specific protease being studied, as its activity and stability can be highly pH-dependent.
What is Serine?
Serine is a conditionally essential amino acid. In other words, humans can synthesize serine under normal nutritional conditions and do not normally need to consume most of the necessary serine in their food. Abbreviated Ser, serine is one of the twenty amino acids that are incorporated into proteins. It is involved in multiple metabolic reactions within the body.
How many molecules of RuBP are required to produce 20 molecules of serine in photorespiration?
In photorespiration, each molecule of serine produced requires one molecule of ribulose bisphosphate (RuBP) to enter the cycle. Since each RuBP can ultimately lead to the production of one molecule of serine, producing 20 molecules of serine would require 20 molecules of RuBP. Therefore, 20 molecules of RuBP are needed to produce 20 molecules of serine in photorespiration.
The catalytic triad common to many serine proteases involves shuttling of protons between what three amino acids?
Ser-his-asp

What is kallikreinkinin?
Kallikreins are biological enzymes of the peptidase (or protease) group. They cleave the peptide bonds in proteins. More specifically, they are "serine" proteases because they cleave the peptide bond at a site in the protein where there is a serine (an amino acid) molecule.

What is pepstatin?
Pepstatin A is an inhibitor of acid proteases (aspartyl peptidases). It forms a 1:1 complex with proteases such as pepsin, renin, cathepsin D, bovine chymosin, and protease B (Aspergillus niger). The inhibitor is highly selective and does not inhibit thiol proteases, neutral proteases or serine proteases. Solublized Beta-secretase and retroviral protease are also inhibited by Pepstatin A. It has been used to characterize proteases from several sources. Pepstatin A is thought to inhibit by a collected-substrate inhibition mechanism.
