#1: DNA chain | Mass: 1544.061 Da / Num. of mol.: 6 / Source method: obtained synthetically Details: DNA consists of four ATGGA repeats. Packing of DNA into crystal structure leads to the presence of three antiparallel AATGG duplexes in the asymmetric unit. Source: (synth.) Homo sapiens (human) #2: Chemical | ChemComp-ACT / | #3: Chemical | ChemComp-MG / | #4: Water | ChemComp-HOH / | Has ligand of interest | N | Sequence details | The full DNA sequence is d(ATGGA)4 which forms self complimentary duplex. Due to the repetitive ...The full DNA sequence is d(ATGGA)4 which forms self complimentary duplex. Due to the repetitive nature and symmetry of such duplex, the asymmetric unit only includes 1/4 of the duplex, with the sequences AATGG. There are three such duplexes in the ASU. | |
