Helical Repeats of Left-Handed DNA
《Open Journal of Molecular and Integrative Physiology》2014年第2期20-26,共7页Youcheng Xu 
DNA is generally assumed as a right-handed double helix and Z-DNA is a special kind of left-handed DNA infrequently found in nature. However, the finding of a zero linking number topoisomer supports a hypothesis that ...

<i>In-Vitro</i>Inhibitory Effect of Methanol Extracts of Chinese Herbal Drugs on Supercoiling Activity of Bacterial DNA Gyrase
《Chinese Medicine》2013年第1期19-23,共5页Hui Xu Huizhi Chen Pan Yao Guodong Lin Weiwen Chen 
A large number of Chinese herbal drugs (CHDs) exhibit antibacterial activities both in vivo and in vitro, but until now little is known regarding their inhibitory mechanisms. Bacterial DNA gyrase is a proven target fo...

SPATIAL WRITHING OF DNA LOOPS RESULTING FROM AXIAL TWIST
《Chinese Science Bulletin》1991年第22期1921-1925,共5页郝鸣鸿 
In vivo DNA often appears in supercoiled states. This phenomenon is related to the constraints imposed on DNA structures, such as co-valenced ring closure, protein binding. When a certain amount of supercoiling isconf...
