| Outline of Final Research Achievements |
Prolyl tripeptidyl peptidase (PTP) from P. gingivalis is a key enzyme of periodontitis. After screening of natural products, rice bran had high inhibitory activity for PTP. The inhibitor protein (PTPI) was purified from rice bran. By MALDI-TOF MS and database of rice, gene Os05g0323900 was identified as the PTP inhibitor. The protein was expressed as fuson protein with thioredoxin, rPTPI-Trx, in E. coli.,and crystallized by the sitting drop vapor diffusion method
