Many antibiotics are effective as drugs to fight off bacterial infections because they inhibit protein synthesis in bacterial cells. Using the information provided in the following table that highlights several antibiotics and their mode of action, discuss which phase of translation is inhibited: initiation, elongation, or termination. What other components of the translational machinery could be targeted to inhibit bacterial protein synthesis?

Hi everyone. Let's take a look at this practice problem together. Streptomycin inhibits pro carry ah tick protein synthesis by binding to the 30 S rivals almost sub unit identify which phase of translation will be affected. So streptomycin is an antibiotic used to treat bacterial infections and recall that this 30 S rivals. So most sub unit is found in pro carry ah tick cells. Only the eukaryotic and pro periodic ribosomes are different. So this is a diagram of a pro periodic ribosomes. It is comprised of the 50 S. Sub unit and the 30 S sub unit. Now that 30 S subunit is what, along with other factors binds to the Shine del Garneau sequence and with other components it initiates translation. So strep to Meyssan will affect initiation and so our answer is going to be a initiation. Alright everyone. I hope you found this helpful and I'll see you soon for the next practice problem.
