Figure 12
Figure 12 Two unique sets of contacts between Mtr4p and a short poly(A) substrate. In two independent monomers in the asymmetric unit of the crystal structure (RCSBID: 2XGJ), two different sets of interactions with adenine bases at the 3′-end of the bound RNA are observed. A: In monomer 1, R1030 interacts with the exocyclic amino group of A5; B: In monomer 2, E947 interacts with the exocyclic amino group of A4 and R1030 interacts with the N3 nitrogen of A5.
