Transpeptidase is an enzyme that catalyzes the formation of peptide bonds between amino acids, playing a crucial role in the synthesis of bacterial cell walls. It is particularly important in the cross-linking of peptidoglycan strands, which provides structural integrity to bacterial cells. Inhibitors of transpeptidase, such as beta-lactam antibiotics, are widely used in medicine to combat bacterial infections by disrupting cell wall synthesis.
What else can I help you with?
Will treatment with transpeptidase eliminate gram positive and gram negative bacteria?
no
Gamma glutamyl transpeptidase (GGT)?
often used with elevated alkaline phosphatase to clarify
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
(GGTP or GGT) Gama Glutamyl transpeptidase?
Confirms findings of increase in ALP to the effect of cholestasis.....probably think bone if the GGTP comes back normal and they aren't pregnant

Can treatment with Transpeptidase eliminate gram positive bacteria from a mixture of gram positive bacteria and gram negative bacteria?
No. A treatment of ethylenediaminetetraacetic acid (EDTA) and the enzyme, lysozyme, will cause gram negative bacteria to lyse. Some gram positive bacteria can also be lysed by doing this. The EDTA stabilizes the solution and allows lysozyme to cut the bonds between the carbohydrates that make up the cell wall wall in bacteria. This will lyse the cell and cause the contents of the cell to be spilled out. This technique is primarily used for DNA assays. A good way to isolate either gram positive or gram negative is by using different types of agar. The MacConkey agarmight be the most useful for what you want to do. It will only allow gram negative to grow, isolating just the gram negatives only.
How do penicillins kill bacteria and what is the mechanism behind their antibacterial action?
Penicillins kill bacteria by disrupting the cell wall synthesis process. They work by inhibiting the enzyme transpeptidase, which is responsible for cross-linking the peptidoglycan chains in the bacterial cell wall. This weakens the cell wall, leading to cell lysis and ultimately bacterial death.
What is ggtp?
GGTp, or gamma-glutamyl transpeptidase, is an enzyme found in various tissues, primarily in the liver. It plays a crucial role in the metabolism of glutathione and the transfer of amino acids across cell membranes. Elevated levels of GGTp in the blood can indicate liver disease, bile duct obstructions, or excessive alcohol consumption. It is often measured in liver function tests to assess liver health.
What antibotic inhibits the crossing of the peptidoglycan?
Penicillin is an antibiotic that inhibits the synthesis of peptidoglycan, a crucial component of bacterial cell walls. It does this by targeting and inhibiting the enzyme transpeptidase, which is essential for cross-linking the peptidoglycan layers. This disruption weakens the bacterial cell wall, ultimately leading to cell lysis and death, particularly in actively dividing bacteria. Other beta-lactam antibiotics also share this mechanism of action.
What is the difference between penicilin and streptomycin?
Peniciilin is derived from Penicillium chrysogenum and is active against Gram-positive bacteria. It connects peptidoglycan strands by irreversibly interacting with transpeptidase and prohibits the last cell wall synthesis. Streptomycin-sulfate is derived from Streptomyces griseusan and is an aminoglycoside antibiotic. It is active against Gram-negative bacteria and Mycobacteria and inhibits initiation of the protein biosynthesis. Penicillin and Streptomycin are often used together.
How penicillin affect bacteria cell?
Penicillin affects bacteria by inhibiting the synthesis of their cell walls. It specifically targets the enzyme transpeptidase, which is crucial for cross-linking peptidoglycan layers in bacterial cell walls. Without a functional cell wall, bacteria cannot maintain their structural integrity, leading to cell lysis and death, especially in actively dividing cells. This makes penicillin effective against many gram-positive bacteria.
What does high gamma gt in blood mean?
The liver is a sort of chemical factory that makes some things that are essential to use in the body and it also breaks down and gets rid of some of the unwanted products of your body's chemical processes.Some liver function tests, like the gamma GT (gamma-glytamyl transpeptidase), are very sensitive and can be raised by something as simple as taking paracetamol regularly and perhaps a bit too often, or as complicated as showing damage caused by too much alcohol.Other liver function tests can be abnormal if certain drugs are making the chemical factory work too hard, or if the liver is being damaged by drugs.Or it could mean that the liver is affected by an infection, like a viral hepatitis or damaged by some other disease process.
