WebTallysomycin is an antitumor antibiotic that is structurally related to bleomycin. The mechanism of action of tallysomycin appears to be similar to that of bleomycin. Bleomycin induces strand scission of puri- fied isolated DNA [ l--5]. Bleomycin has also been shown to produce breakage of intracellular DNA [5,6]. WebThe cloned gene cluster in TLM biosynthesis was confirmed by inactivating the tlmE glycosyltransferase gene to generate a TLM non-producing mutant and by restoring TLM production to the DeltatlmE::ermE mutant strain upon expressing a functional copy of tlME. The tallysomycins (TLMs) belong to the bleomycin (BLM) family of antitumor antibiotics. … hayes ivy manufacturing inc

Web29 Dec 1978 · Tallysomycin (TLM), an experimental glycopeptide antitumor antibiotic related to bleomycin (BLM), at a concentration of 4.8 × 10 −5 M sequesters Fe 2+ and nicks circular DNA to 75–80 per cent in 45 min. The DNA scission reaction which requires oxygen and is suppressed by other divalent ions and by EDTA is pH dependent and shows optima … Web1 Nov 1990 · In the iron-tallysomycin complex solutions, the iron concentration was slightly less than the stoichiometric amount to ensure that no free iron exists in the systems; the typical iron/TLM ratio used was 0.9. In systems containing DNA, the concentration of nucleic acid used was equal to that of iron-tallysomycin complex. WebTallysomycins (TLMs) belong to the bleomycin (BLM) family of anticancer antibiotics and differ from the BLMs principally by the presence of a 4-amino-4,6-dideoxy-L-talose attached to C-41 of the TLM backbone as part of a glycosylcarbinolamide.
