A combinatorial selective labeling (CSL) method is presented for the assignment of backbone amide NMR resonances, which has a particular application in the identification of protein-ligand interaction sites. The method builds on the dual amino acid selective labeling technique. In the CSL method a number of different samples are produced, each with a different pattern of labeled amino acids. By analyzing peak intensities in HSQC and 2D HNCO spectra of these samples, a large number of combinations of amino acid pairs can be simultaneously assigned. We demonstrate the method on the 27 kDa protein GFP. The samples can be produced rapidly and cost-effectively in a commercially available in vitro translation system. The method greatly simplifies the process of backbone assignment and would be very straightforward to automate.

Combinatorial triple-selective labeling as a tool to assist membrane protein backbone resonance assignment Combinatorial triple-selective labeling as a tool to assist membrane protein backbone resonance assignment Abstract Obtaining NMR assignments for slowly tumbling molecules such as detergent-solubilized membrane proteins is often compromised by low sensitivity as well as spectral overlap. Both problems can be addressed by amino-acid specific isotope labeling in conjunction with 15Nâ??1H correlation experiments. In this work an extended combinatorial selective in vitro labeling scheme is proposed that seeks to reduce the number of samples required for assignment.
