Description:
The carcinogen aflatoxin B1 was reacted with a polymer of alternating deoxyguanine and deoxycytosine residues to determine the effect that adduct formation has on the conversion of this polymer from the right-handed B-DNA form found at low salt concentrations to the left-handed Z-DNA form found at high salt concentrations. Reaction with aflatoxin strongly inhibited the salt-induced conversion of this polymer from B-DNA to Z-DNA. This inhibition could be detected even at relatively low binding levels.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Nordheim, A -- Hao, W M -- Wogan, G N -- Rich, A -- New York, N.Y. -- Science. 1983 Mar 25;219(4591):1434-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6402818" target="_blank"〉PubMed〈/a〉
