WebJan 1, 1988 · Dityromycin is a peptide antibiotic isolated from the culture broth of the soil microorganism, Streptomyces sp. strain No. AM-2504, showing activities against Bacillus, , and . Dityromycin was clarified to be composed of N-MeVal, Pro, Val, Phenylglycine, CH NH, N,N-Me Thr and di-α-amino acid containing diphenylether moiety. http://perspectivesinmedicine.cshlp.org/content/6/9/a025361.full.pdf
WebPeptides with these mechanisms include edeine [96,97], tuberactinomycins [98], and dityromycin [99]. Edeine is an antimicrobial pentapeptide that binds to the binding site (P-site) of both 30S subunits and 70S ribosomes, thus inhibiting the binding of aminoacyl-tRNA and blocking translation initiation [96,97]. Tuberactinomycins, a group of ... WebThe mechanism by which the closely related decapeptide antibiotics dityromycin and GE82832 inhibit EF-G-catalyzed translocation is elucidated in this study.
