Chemical shift assignments of RHE_RS02845, a NTF2-like domain-containing protein from Rhizobium etli.

The nuclear transport factor 2 (NTF2) like superfamily includes members of the NTF2 family, delta-5-3-ketosteroid isomerases, and the beta subunit of ring hydroxygenases. This family plays important roles in both eukaryotic and prokaryotic cells, and is taken as a classic example of divergent evolution because proteins in this family exhibit diverse biological functions, although share common structural features. We cloned the gene RHE_RS02845 encoding a predicted NTF2-like domain-containing protein in Rhizobium etli, and prepared U-13 C/15 N-labeled protein samples for its three-dimensional NMR structural determination. Here, chemical shift assignments for both backbone and side-chain atoms are reported, which is prerequisite for further structural calculation and functional research using NMR spectroscopy.
