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 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.
Is serine polar?
Yes serine is a polar amino acid as it has an hydroxyl group (OH-) attached to the r group.
Which enzyme the hydrolyzes protein?
Amylase hydrolyzes carbohydrates, lipases breakdown lipids/fats, and proteases break down protein.
What is the structure of N-serine in a neutral solution?
Serine is found in several configurations: L-serine, beta-Hydroxyalanine, (S)-Serine, 56-45-1, L-ser, (S)-2-Amino-3-hydroxypropanoic acid and D-ser. It is a non-essential amino acid occurring in natural form as the L-isomer. It is synthesized from GLYCINE or THREONINE. HO2CCH(NH2)CH2OH. (2S)-2-amino-3-hydroxypropanoic acid D-Serine, synthesized in the brain by serine racemase from L-serine (its enantiomer), serves as a neuromodulator by coactivating NMDA receptors, making them able to open if they then also bind glutamate. D-serine is a potent agonist at the glycine site of the NMDA-type glutamate receptor. D-serine was only thought to exist in bacteria until relatively recently; it was the second D amino acid discovered to naturally exist in humans, present as a signaling molecule in the brain, soon after the discovery of D-aspartate. D-Serine is being studied in rodents as a potential treatment for schizophrenia and L-serine is in FDA-approved human clinical trials as a possible treatment for ALS

The catalytic triad common to many serine proteases involves shuttling of protons between what three amino acids?
Ser-his-asp
What has the author Joanne C Krupa written?
Joanne C. Krupa has written: 'Geometric isomer discrimination capabilities of serine proteases'
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.
How tall is Mariah Serine?
Mariah Serine is 5' 6".
What are the actions of serine dehydratase?
The serine dehydratase is an enzyme; enzymes act as catalysts in biochemical reactions. Role of serine dehydratase: - transformation of serine in pyruvate - transformation of threonine in propionyl CoA
When was Carolyn SeRine born?
Carolyn SeRine was born in Salem, in Oregan, USA.

How does a serine molecule differ from a cysteine molecule?
A serine molecule contains information a different number of
How many non bonding electron pairs are in serine?
Serine does not have any non-bonding electrons pairs. Please click on the related link to see a structural formula for serine.
Why don't proteases act on gut walls and digest?
It is because proteases work only on proteins.
