Theoretical study on the structure, stability, and electronic properties of the guanine-Zn-cytosine base pair in M-DNA

Article Abstract:

A comprehensive ab initio study is used to observe and analyze the structure, stability and electronic properties of guanine-zinc-cytosine (G-Zn-C) base pair, which when combined with metals like Zn and Co lead to the formation of M-DNA at high values of pH. The analysis suggest that a lot of things should be taken care of while studying the electronic properties of such base-pairs, as M-DNAs with functionals do not account for strong electronic correlations.

Electronic structure of xDNA

Article Abstract:

The results from investigation of the electronic properties of an xDNA duplex made of natural and benzo-homologated bases and a natural one with an analogous sequence suggest that xDNA has a smaller [pi]-[pi]* gap than B-DNA suggests and could be used as plausible candidate for molecular-wire applications.
