QUICK LINKS

Spiramycin is a macrolide antibiotic produced by Streptomyces ambofaciens. It is composed of a large lactone ring to which one or more deoxy sugars are attached. Spiramycin inhibits bacterial protein synthesis by binding to the 50S ribosomal subunit, thus preventing the translocation of peptidyl-tRNA from the A-site to the P-site. This ultimately leads to the inhibition of bacterial growth.
