Kirromycin

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.
