Aminoglycoside is a medicinal and bacteriologic category of traditional Gram-negative antibacterial medications that inhibit protein synthesis and contain as a portion of the molecule an amino-modified glycoside .
Aminoglycoside-3'-phosphotransferase (APH(3')), also known as aminoglycoside kinase, is an enzyme that primarily catalyzes the addition of phosphate from ATP to the 3'-hydroxyl group of a 4,6-disubstituted aminoglycoside, such as kanamycin. [2]
G418 (geneticin) is an aminoglycoside antibiotic similar in structure to gentamicin B1.It is produced by Micromonospora rhodorangea. [1] G418 blocks polypeptide synthesis by inhibiting the elongation step in both prokaryotic and eukaryotic cells. [1]
Kanamycin is in the aminoglycoside family of medications. [3] It has the weakest antibacterial capabilities of all compounds in this family when used clinically, which is partially due to its increased toxicity in comparison to other aminoglycosides. [5] It works by blocking the production of proteins that are required for bacterial survival. [3]
Neomycin is an aminoglycoside antibiotic that displays bactericidal activity against Gram-negative aerobic bacilli and some anaerobic bacilli where resistance has not yet arisen. It is generally not effective against Gram-positive bacilli and anaerobic Gram-negative bacilli. Neomycin comes in oral and topical formulations, including creams ...
Hygromycin B was originally developed in the 1950s for use with animals and is still added into swine and chicken feed as an anthelmintic or anti-worming agent (product name: Hygromix). Hygromycin B is produced by Streptomyces hygroscopicus, a bacterium isolated in 1953 from a soil sample. Resistance genes were discovered in the early 1980s.
In enzymology, an aminoglycoside N6'-acetyltransferase (EC 2.3.1.82) is an enzyme that catalyzes the chemical reaction. acetyl-CoA + kanamycin-B CoA + N 6 '-acetylkanamycin-B. Thus, the two substrates of this enzyme are acetyl-CoA and kanamycin B, whereas its two products are CoA and N6'-acetylkanamycin-B.
Glucosamine. In organic chemistry, an amino sugar is a sugar molecule in which a hydroxyl group has been replaced with an amine group.More than 60 amino sugars are known, with one of the most abundant being N-acetyl-D-glucosamine (a 2-amino-2-deoxysugar), which is the main component of chitin.
