PROTEASE: função e aplicação Proteases representam uma classe de enzimas com importantes papéis em processos fisiológicos. Além disto, elas possuem aplicação comercial, estando entre os três maiores grupos de enzimas industriais, sendo responsáveis por 60% da venda internacional de enzimas.
Add the following to a microcentrifuge tube: Fusion Protein 20 µg 10X SUMO Protease Buffer +/- Salt 20 µl Water to 190 µl SUMO Protease (10 units) 10 µl Total volume 200 µl 2. Mix and incubate at 30°C. Remove 20 µl aliquots at 1, 2, 4, and 6 hours.
Protease Phosphate buffer Racemic ester (1-2 mmol) and potassium phosphate buffer (0.1 M, pH 7.0, 5 mL) is homogenized by stirring. Protease Enzyme (50% wt/wt with regards to substrate for solid enzyme or 10-20% v/v with regards to solvent mixture for liquid enzyme) is added under stirring.
Emission maximum in the neutral and alkaline range l = 584 nm, in the acidic range l = 559 nm. Application. The preparation is a general substrate for proteases and is especially well suited for the detection of traces of protease activities.
In this system, it is considered that the amino acid residues of the polypeptide substrate bind in enzyme subsites of the active site. By convention, these subsites on the protease are called S (for subsites) and the substrate amino acid residues are called P (for peptide).

– usually dimeric although pro-enzyme (zymogen) may be monomeric – autocatalysis induces dimerization and activation Picornain – structurally similar to serine protease chymotrypsin but active site ser has been mutated to cys – important for the spread of hepatitis A
The activity of serine protease (trypsin) is determined by the rate of enzyme hydrolysis of the substrate chromophoric substrate Ac-Arg-p-nitro-anilide. The liberated p-nitroaniline produces an increase in absorption at 405 nm, directly proportional to the enzyme activity.
