... Cdc6 proteins [60,61]. As can be seen in Fig. 4, both proteins possess N-terminal AAA + domains and C-terminal DNA binding domains (DBDs). In DnaA, the DBD contains a helix-turn-helix; in the archaeal ... also increases the affinity of DnaC for single stranded DNA. In contrast ADP– DnaC does not inhibit DnaB helicase and has lower DNA binding affinity. Thus, it has been proposed th...

In Section 4, we present experi- ments indicating that the expected running time of the new system on naturally occurring data is in fact ... trees by swapping the order of words in the input. Adding the swapping operation changes the time complexity for deterministic parsing from linear to quadratic in the worst case,...
