| Research Abstract |
We have established the E. coli expression system for the full-length human tubulin tyrosine ligase 1 (TTL1). By using co-expression technique, molecular chaperone was co-expressed to improve the solubility of TTL1, and we succeeded in improvement of the yield about 5 times. We also found that the optimal buffer condition for NMR measurement. We have also developed the high-throughput monitoring system using GFP fused TTL1. Meanwhile, we have established the real-time monitoring system of TTL1 activity by NMR.
