... 2331 in vitro model in order to investigate some of the fea- tures of the polyamine–phosphate interactions. Specifi- cally, we examined the role played by each polyamine in the self-assembly of in ... recoveries of polyamines in ivNAPs. Polyamines were quantified by RP-HPLC after derivatiza- tion with dansyl chloride. In vitro NAPs were in this case obtained by pooling 48 m M...

We previ- ously performed single amino acid substitutions in the C-terminal domain ... HIV IN proteins result in proteins de cient in multimerization [31,34] and specific mutations in the C-terminal domain inhibit the oligomerization of HIV-1 IN [39,40]. Conversely...
