FIGURE 2.
Structural Overviews of the E. coli (DinJ)2-(YafQ)2 complex and YafQ. A, overview of the (DinJ)2-(YafQ)2 heterotetramer. YafQ is shown in cyan or yellow (YafQ′), and DinJ is shown in green or magenta (DinJ′). Secondary structure elements in DinJ and YafQ are indicated. B, close-up view of the caged sulfate coordinated at the presumed catalytic site in YafQ and the linker (α2-α3) of DinJ. C, overview of the YafQ (in blue) and YafQ(H87Q) (in pink) structure and structural comparison. D, superimposition of free YafQ structure with A. oryzae RNase T1 (gray) in complex with GpU (Protein Data Bank entry 1B2M). All representations were prepared in PyMOL.
