Ribostamycin is an aminoglycoside antibiotic. The in vitro activity of ribostamycin against algae of the genus Prototheca was evaluated by minimum inhibitory concentration (MIC) studies on solid media. Ribostamycin is an aminoglycoside antibiotic. Aminoglycosides work by binding to the bacterial 30S ribosomal subunit (some work by binding to the 50S subunit), inhibiting the translocation of the peptidyl-tRNA from the A-site to the P-site and also causing misreading of mRNA, leaving the bacterium unable to synthesize proteins vital to its growth. Aminoglycosides, such as ribostamycin, bind to the bacterial 30S and 50S ribosomal subunit, which inhibits the translocation of the peptidyl-tRNA from the A-site to the P-site. This causes misreading of mRNA which makes bacteria unable to make essential proteins. It also inhibits the chaperone activity of protein disulfide isomerase (PDI). ...
