| Research Abstract |
We successfully prepared protein and RNA molecules which are required for selecocystein incorporation on ribosome. These molecules are SBP2, L30, EFSec, SEICIS-RNA, tRNASec and subjected to biochemical and biophysical experiments. Crystal structure of L30 could be analyzed and published. Since we originally succeeded generating functional tRNASec, binding assay among tRNASec, EFSec, and SBP2 in the presence of specific amino acid are now in progress. We observed the significant binding affinity(K_d=229 nM) between the wild type and GDP using ITC, the way to prepare the molecule was thus confirmed. Furthermore, mutants generated for the purpose of crystallization were proved that they have proper secondary structures
