- 11:08Conclusion
Kristalstructuur van eiwit-DNA-complexen kan inzicht verschaffen in eiwitfunctie, mechanisme, evenals de aard van de specifieke interactie. Hier rapporteren we hoe de lengte en sequentie uiteinden van duplex DNA optimaliseren voor co-kristallisatie met<em> Escherichia coli</em> SeqA, een negatieve regulator van replicatie-initiatie.
