... shown that their N-terminus modulates their activity [36,37]. The current hypothesis involves domain–domain interac- tions between the N-terminus and other domains of the ATPase. Indeed, in vitro ... studies of the purified N-terminus and catalytic loop of the Wilson ATPase have shown that these two domains interact in the absence of copper and that their interact...

... oxygen of the main chain at Asp266 was bound to amino groups of main chain of Tyr269 and Ala270 by hydrogen bonds. The interactions should maintain the structure of the C-terminal region. In the ... region on the opposite side of the N-terminal region on the molecular surface. In the wild- type enzyme, the side chain of Asp266 interacted with the amin...

The binding of the homodimer of HCF152 in this region somehow stabilizes the splicing products, possibly by folding the RNA into the correct splicing ... located at the C-terminus of the protein although binding of the C-terminus half (CH) is only half of the full-length protein (Fig. 3). Interestingly, the bin...

... replaced by other residues in the authentic ribose-binding proteins. In addition, the repressor sequences include a DNA-bind- ing headpiece, and so are consistently longer than those of the binding ... protein. This kind of protein is exemplified by the Thermus thermophilus protein, PDB entry 2B3B [28]. The mode of binding the monosaccharide is completely different...
