Details

The protein shows aggregation via the aminoterminal domain, and the resulting line broading of the signals of the aminoterminal domain did not allow a structure determination of the aminoterminal domain using the full length protein. Becuase of flexible linked domains the carboxyterminal domain showed sufficient signals to determine the structure of this domain using the full length protein. Only the carboxyterminal domain (res. 124-181) gave interpretable NMR data for assignment and structure determination.
