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]
Macrolides, [8] clindamycin [12] and aminoglycosides [7] (with all these three having other potential mechanisms of action as well), have evidence of inhibition of ribosomal translocation. Fusidic acid prevents the turnover of elongation factor G from the ribosome.
The binomial name often reflects limited knowledge or hearsay about a species at the time it was named. For instance Pan troglodytes, the chimpanzee, and Troglodytes troglodytes, the wren, are not necessarily cave-dwellers. Sometimes a genus name or specific descriptor is simply the Latin or Greek name for the animal (e.g. Canis is Latin for ...
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]
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.
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]
