WebJun 1, 1991 · Classes of G-quartet structures The major guanine-quartet structures formed by DNA oligomers, examples of which are shown in Fig. 1, are: tetramolecular parallel quadriplexes (G4-DNA) [5,10.]; unimolecular antiparaUel quadriplexes (which we may term G4'-DNA) [6,7.,11",12.]; and, bimolecular anti- parallel quadriplexes (G'2-DNA) [7.,9o]. WebAug 9, 2007 · A G quartet is formed from four guanine residues arranged in a planar configuration, which is stabilized by Hoogsteen-type hydrogen bonds. Several such planar structures can stack and are stabilized by potassium or sodium cations, but they do not form in the presence of lithium cations ( 20–22 ). WebNov 9, 2015 · The G-vacancy can be filled up by a guanine base from GTP or GMP to complete an intact G-quartet by Hoogsteen hydrogen bonding, resulting in significant G-quadruplex stabilization that can effectively alter DNA replication in vitro at physiological concentration of GTP and Mg 2+. tauranga probation phone
