Figure 4

Mobile loop movement of UGM with UDP-Galf 1 in conformation A. Starting positions of the mobile loop ribbon and Arg 174 are shown in purple. Arg 174 on the mobile loop approaches the alpha phosphate of UDP-Galf 1 during the first 1.5 ns of simulation and remains near this orientation for the remaining 2.5 ns. FAD and Trp 160 are also displayed. The latter interacts with the uracil moiety.
