Description
Curator's Comment: description was created based on several sources, including https://www.ncbi.nlm.nih.gov/pubmed/994327

Mocimycin (also known as kyrromycin) was isolated from Streptomyces ramocissimus and tested in vitro against wide range of bacterias. Although having showed good results, drug did not enter clinical trials. Mocimycin acts by binding tightly and specifically to bacterial EF-Tu. Upon administration the antibiotic prevents EF-Tu-GDP from leaving the ribosome and thus inhibits bacterial protein synthesis. Nowadays, the antibiotic is mainly used to study bacterial protein synthesis at the level of elongation factor EF-Tu-GDP release.
