Kristallstruktur von Protein-DNA-Komplexe können Einblick in Proteinfunktion, Mechanismus, sowie, die Natur der spezifischen Wechselwirkung bereitzustellen. Hier berichten wir, wie die Länge, Sequenz und Enden der DNA-Doppelstrang für Co-Kristallisation zu optimieren mit<em> Escherichia coli</em> SeqA, ein negativer Regulator der Replikation Initiation.
