Stl recognition of monomeric Duts. (A) Model of monomeric Dut-Stl^N-ter complex. (Left) Cartoon representation of the _EBVDut-Stl^N-ter model with Dut and Stl colored in green and cyan, respectively. (Right) Close-up view of the monomeric Dut active center where the Stl is accommodated, showing in stick form the residues involved in Dut-Stl interactions. (B) Stl inhibits _EBVDut activity. The enzymatic activity of _EBVDut as production of P_i was calculated in the absence (black) or presence (red) of Stl^N-ter. The graph shows the results and standard deviations from three independent assays.
