How is enzyme catalysis achieved? What does an enzyme actually do to its substrate to catalyze its modification or breakdown? How does an enzyme lower the energy of activation for a reaction? What kinds of reactions do the following classes of enzymes catalyze? (a) Hydrolases (b) Lyases (c...
Explain the following enzyme and what type of reaction they catalyze: (a) Glucose-6-phosphatase (b) Glycogen phosphorylase Proteins are cleaved (cut) by proteases. How do these enzymes work? (a) Proteases cleave any carbon-carbon bond that tou...

inactive conformation. Once they reach to the site of action, the self-inactivating “prodomain” peptide is removed to put them into operation. In the case of i-CLiPs-mediatedproteolytic processing, because both enzymes and substrates known to date are all membrane proteins as mentioned above, ...
Alternatively, if there were nonprotein cofactors acting as a molecular scaffold which contributed to the protease resistance of aggregated PrP,37, 38, 39 partial denaturation in an acidic compartment might enable cellular enzymes to degrade them, thus leading to an increased susceptibility to ...
Proteases make up a large category of enzymes, including endopeptidases and exopeptidases, which catalyze the hydrolytic breakdown of proteins into peptides or amino acids in a wide variety of cell and tissue types. Proteases are regulated and compartmentalized in living cells, but cell lysis ...
Aspartic proteases, also known as aspartyl proteases and aspartic endopeptidases, are a group of protease enzymes that use two highly conserved aspartic acid residues in the active site for catalytic cleavage of their peptide substrates. Unlikeserineorcysteine proteases, these proteases do not form a...
It is one of the three deubiquitinating enzymes that bind to proteasome and can interact dynamically with proteins through ubiquitin. They regulate the function, metabolism, and degradation of proteins in the body, thus affecting a series of life activities such as the cell cycle, cell ...
Humans do not contain the enzymes to break down what? Beta-lactamases are which of the following? a. Enzymes that break down cell walls. b. Enzymes that break down aminoglycosides. c. Enzymes that break down ampicillin. d. Enzymes that break sown quinolones. Which enzymes break down cellulose...
Which of the following is not an enzyme? A. Oxytocin B. Trypsin C. Pepsin D. PtyalinSalivary amylase digests: A. proteins B. polypeptides C. carbohydrates D. vitamins E. lipidsName the enzymes that would digest proteins, lipids, and carbohydrates....
