(a) Overview of the 2.4 Å resolution crystal structure of ctMex67RRM. (b) A schematic illustration of the secondary-structural elements present in the RRM domain, which showed the characteristic βαββαβ fold. The RRM domain from ctMex67 had a short β-strand prior to β4 that was not found in other organisms (denoted β4′). (c) Three representative views of the final 2Fo − Fc maps for the ctMex67RRM structure contoured at the 1σ level. (d) Overview of the 1.7 Å resolution crystal structure of ctMex67LRR. (e) Schematic illustration of the secondary-structural elements present in the LRR domain whereby tandem repeating α-helices and β-sheets generate a curved structure. Disordered regions are shown as red dotted lines. The LRR domain from ctMex67 includes an extra helix insertion between α2b and β2 when compared with the H. sapiens homologue. (f) Three representative views of the final 2Fo − Fc maps for the ctMex67LRR structure contoured at the 1σ level. |
