How does penicillin work as an enzyme inhibitor?
Penicillin works by irreversibly inhibiting an enzyme (transpeptidase) that catalyzes a crosslinking reaction in the formation of the bacterial cell wall. Penicillin inhibits the transpeptidase by forming an irreversible covalent bond with the active-site serine residue in the enzyme
What enzyme does Bacteriophages use to breach bacterial cell wall?
Bacteriophages use lysozyme, an enzyme that degrades peptidoglycan in the bacterial cell wall, to breach the bacterial cell wall and gain entry into the host cell. This allows the phage to inject its genetic material into the bacterium and replicate.
Which bacterial enzyme is responsible for the first reaction involved in the conversion of starch into glucose?
Alpha-amylase is the bacterial enzyme responsible for the initial breakdown of starch into maltose, which is then further broken down into glucose by other enzymes.
What enzyme prevents bacterial growth in the mouth?
Lysozyme is the enzyme that helps prevent bacterial growth in the mouth. It is found in saliva and works by breaking down the cell walls of bacteria, leading to their destruction. This antimicrobial action contributes to maintaining oral health by controlling bacterial populations and reducing the risk of infections.
What r bacterial aggressins?
bacterial agressins are molecules that the bacteria "shoot" at phagocytic molecules. Some agressin molecules include streptolysin O, leukocidin (staphylococcus), extoxin A, adenylate cyclase, and anthrax toxin EF
What enzyme inhibits bacterial growth?
polymerase
Which enzyme is Known as Genetical or Genetic Knife?
restriction endonuclase enzyme (made in bacterial plasmids)
What enzyme in saliva inhibits bacterial growth?
Lysoszyme
What enzyme is coded forin the chromosome of bacteria?
One common enzyme coded for in the chromosome of bacteria is DNA polymerase, which is responsible for replicating the bacterial DNA during cell division. This enzyme is essential for maintaining the integrity of the bacterial genome.

What is an acetylglucosaminyltransferase?
An acetylglucosaminyltransferase is an enzyme which adds acetylglucosamine to heptose residues of bacterial cell walls.
What is the function of DNA gyrase?
DNA gyrase is a bacterial enzyme which introduces supercoils into the bacterial DNA, resulting in a highly condensed 3-dimentional struture. it is also known as Topoisomerase. Quinolones and F/Quinolones inhibit this enzyme and thus interfere with bacterial DNA replication. The enzyme is absent in humans.

Is sulfonamide a non competative inhibitor?
No, sulfonamides are not non-competitive inhibitors; they are competitive inhibitors. Sulfonamides mimic para-aminobenzoic acid (PABA), a substrate for bacterial enzyme dihydropteroate synthase, thus competing with PABA for binding to the enzyme. This competitive inhibition prevents the synthesis of folate, which is essential for bacterial growth.
