Figure 5.

Figure 5

5-formylTHHF, in position to attack the γ-phosphate of ATP. THHF and ATP are shown with dark CPK coloring and MTHFS with lighter CPK coloring, except for Y151 (on the left) and Y152 (at the top), whose side-chains are colored green. The THHF formyl group is shown in magenta. The distance between THHF N11 and Y151 Cδ1 is shown to indicate that this placement of THHF is only possible if the side-chain of Y151 is removed. The figure was rendered using Molscript and Raster3D.
