DERMOTRACIN AEROSOL POWDER 150 ML

Mechanism of Action of Bacitracin Bacitracin is an antibiotic produced by the strain of Bacillus subtilis. It acts by inhibiting bacterial cell wall synthesis. It is active against a variety of gram positive and a few gram negative organisms. Mechanism of Action of Neomycin Aminoglycosides like neomycin "irreversibly" bind to specific 30S-subunit proteins and 16S rRNA. Specifically neomycin binds to four nucleotides of 16S rRNA and a single amino acid of protein S12. This interferes with decoding site in the vicinity of nucleotide 1400 in 16S rRNA of 30S subunit. This region interacts with the wobble base in the anticodon of tRNA. This leads to interference with the initiation complex misreading of mRNA so incorrect amino acids are inserted into the polypeptide leading to nonfunctional or toxic peptides and the breakup of polysomes into nonfunctional monosomes.
