  • Antibiotic. Member of the elfermycin group.
  • Antibacterial.
  • Protein biosynthesis inhibitor.
  • Specifically interacts with the bacterial elongation factor EF-Tu and prevents the release of EF-Tu from the bacterial ribosome after GTP hydrolysis. In the absence of ribosomes it induces EF-Tu-dependent hydrolysis of GTP.
  • Animal growth promoter used in poultry breeding.
