Figure 1.
Structure of pol II TFIIB complex. (A) "Top" view of pol II in a surface representation, with previously identified domains in the colors indicated, and with TFIIB in ribbon representation. TFIIB zinc ribbon (TFIIB[N]), linker (TFIIB[L]), first cyclin repeat (TFIIB[C]) are indicated. (B) Difference (F[o]-F[c]) electron density map between pol II TFIIB and pol II alone, contoured at 2.0[sigma], shown in green mesh, and Se-Met anomalous peaks, contoured at 6-10[sigma], shown in blue mesh.
