The D form was more potent than the F form against drug-resistant Enterobacterales and other bacterial species but caused renal toxicity at a lower dose. After crossing both membranes barriers, the antibiotic enters the cytoplasm and targets the ribosome. Therefore, its structure is rooted in the streptothricin molecular structure composed of a carbamulated D-glucosamine sugar, a streptolidine lactam, and a B-lysine homopolymer. The opinions expressed here are the views of the writer and do not necessarily reflect the views and opinions of News Medical. 5. Our studies help explain how this antibiotic confuses the machinery so that the message is read incorrectly, and it starts to put together gibberish.
