Erythromycin A dihydrate is extensively employed in biological research to explore its interaction with bacterial ribosomes. It serves as a useful tool for probing the structure and function of the ribosomal exit tunnel, where it is known to bind and inhibit protein synthesis. Studies involving Erythromycin A dihydrate often focus on the molecular basis of ribosome selectivity and the inhibition mechanism that leads to the cessation of bacterial growth. This compound is also utilized in investigating the development of bacterial resistance mechanisms. In addition, it facilitates the study of ribosome conformational changes upon antibiotic binding, which is for understanding the translational regulation in prokaryotic organisms.
