== Publication Abstract from PubMed == | |||
Paramagnetic lanthanide ions fixed in a protein frame induce several paramagnetic effects such as pseudo-contact shifts and residual dipolar couplings. These effects provide long-range distance and angular information for proteins and, therefore, are valuable in protein structural analysis. However, until recently this approach had been restricted to metal-binding proteins, but now it has become applicable to non-metalloproteins through the use of a lanthanide-binding tag. Here we report a lanthanide-binding peptide tag anchored via two points to the target proteins. Compared to conventional single-point attached tags, the two-point linked tag provides two to threefold stronger anisotropic effects. Though there is slight residual mobility of the lanthanide-binding tag, the present tag provides a higher anisotropic paramagnetic effect. | |||
Two-point anchoring of a lanthanide-binding peptide to a target protein enhances the paramagnetic anisotropic effect.,Saio T, Ogura K, Yokochi M, Kobashigawa Y, Inagaki F J Biomol NMR. 2009 Jul;44(3):157-66. Epub 2009 May 26. PMID:19468839<ref>PMID:19468839</ref> | |||
