Nucleic Acids in Chemistry and Biology (RSC Publishing)Isobel D. Michael Blackburn, Peter G. Stockley, Probing the molecular mechanism of action of co-repressor in the E. We have studied quantitatively the effect of the corepressor, S-adenosylmethionine SAM , on the interaction between the E. We have recorded kinetic binding data in the presence of SAM, which carries a net positive charge, and two corepressor analogues, adenosylornithine AO and aza-SAM, which differ in the location of the atom carrying the positive charge. Our data support the hypothesis that the effect of the corepressor is electrostatic in origin. These results illustrate the potential of SPR measurements for studying protein-nucleic acid interactions.

Nucleic Acids: DNA and RNA
The book does a great job of communicating the excitement of research on nucleic acids. My search for a textbook for next year's nucleic acids course appears to be over! Jennifer A. Du kanske gillar. Inbunden Engelska, Spara som favorit. Skickas inom vardagar.
Hanna M, G! The unique material properties of DNA have made it an attractive molecule for material scientists and engineers interested in micro- and nano-fabrication. Crystal structures indicate that achiral PNA can form right-handed and left-handed P-type helices Google Scholar Stotzky, M. Google Scholar Mortland, Szostak JW.
Synthetic genetics is a subdiscipline of synthetic biology that aims to develop artificial genetic polymers also referred to as xeno-nucleic acids or XNAs that can replicate in vitro and eventually in model cellular organisms. This field of science combines organic chemistry with polymerase engineering to create alternative forms of DNA that can store genetic information and evolve in response to external stimuli. Practitioners of synthetic genetics postulate that XNA could be used to safeguard synthetic biology organisms by storing genetic information in orthogonal chromosomes. XNA polymers are also under active investigation as a source of nuclease resistant affinity reagents aptamers and catalysts xenozymes with practical applications in disease diagnosis and treatment. In this review, we provide a structural perspective on known antiparallel duplex structures in which at least one strand of the Watson—Crick duplex is composed entirely of XNA. Currently, only a handful of XNA structures have been archived in the Protein Data Bank as compared to the more than structures that are now available.
