The 200K protein dynamical transition is observed for the first time in the terahertz dielectric response. The complex dielectric permittivity ε=ε'+iε" is determined in the 0.2{\textendash}2.0THz and 80{\textendash}294K ranges. ε" has a linear temperature dependence up to 200K then sharply increases. The low temperature linear dependence in ε" suggests anharmonicity for temperatures 80K\<t\<180k, challenging="" the="" assumed="" harmonicity="" below="" 200k.="" temperature="" dependence="" is="" consistent="" with="" thermally="" activated="" sidechain="" motions="" and="" shows="" involved="" in="" dynamical="" transition="" extend="" to="" subpicosecond="" time="" scales.\<="" div=""\>
